GNOME Bugzilla – Bug 661112
banshee window remain white on startup on armel (ArgumentException at Hyena.Gui.Canvas::Size.set_Width )
Last modified: 2012-09-13 19:20:15 UTC
Created attachment 198461 [details] Log of mono --debug /usr/lib/banshee/Banshee.exe On all of the ubuntu 11.10 supported armel platforms, the same issue occurs; Banshee starts, draws a white window with nothing in it, and freezes. The attached logs show that an exception is thrown during Hyena initialization. This bug is also being tracked at https://bugs.launchpad.net/ubuntu/+source/banshee/+bug/857299
Did you try to add some debug statements in CanvasItem.Measure() and the Size constructor ? From looking at the code, I don't see how the exception could happen : The Size constructor is called with values calculated like this : Math.Max (0, <some calculation>) But then the exception is thrown because the value is negative, which should not be possible. Maybe this is some floating point calculation issue that only happens on ARM ? I'll attach a small test case that does basically the same thing as the code in Banshee, could you try to compile and run it ?
Created attachment 198647 [details] Minimal test case Minimal test case that does the same thing as Banshee. Compile with "mono-csc test_max.cs", run with "mono test_max.exe"
Ran attached testcase, program returned "size is 0", no exceptions. I am starting to believe that the exception reported in the failure log is a red herring. See comments on launchpad bug (above).
Thanks for the bug report. This particular bug has already been reported into our bug tracking system, but please feel free to report any further bugs you find. *** This bug has been marked as a duplicate of bug 624976 ***
Oops, I think it's not exactly the same stacktrace.
I just tested the patch attached to bug 624976 and it makes banshee work on arm (omap4 Pandaboard) running Ubuntu Oneiric 11.10, albeit with a lot more noise on the gnome terminal. Will pick apart the patch a little to see exactly what is allowing forward progress to be made, and where the bad data may be coming from, as well as why it is different on arm vs x86 (both images should be nearly identical).

That's good to know! I guess the part that makes it work is the replacement of the ArgumentException with the simple overwrite of the incoming value to 0 in the property setter when it is lower than zero. The bug lies then in the fact that there is somewhere where the property is being set to a negative value. I'll try to look at how this happens in bug 624976, but cannot check why it happens in this case because I don't have an ARM device ready to test! So I hope you can figure out, I can try to help where I can. Thanks
For reference, I can start up Banshee just fine on a Genesi MX ARM netbook upgraded to Oneiric. I haven't spent time testing Banshee extensively on this machine but I am unable to reproduce the problem.
I've just finished installing Linaro's Ubuntu spin on an OMAP4 powered Pandaboard, and tested the default Banshee in Oneric. When connected to my TV via HDMI all I get is a white screen, then the app hangs. What gets interesting is if I ssh into the Pandaboard, I can fire up banshee but it fails to respond properly (oh and it looks ugly, reminds me of GNOME 1.x :) ) Output from terminal is: andrew@linaro-ubuntu-desktop:~$ banshee [Info 21:51:24.826] Running Banshee 2.2.0: [Ubuntu oneiric (development branch) (linux-gnueabi, arm) @ 2011-09-23 05:07:31 UTC] [Warn 21:51:26.607] DBus support could not be started.

Can you check the value of the env var DBUS_SESSION_BUS_ADDRESS. Because it must be set but seems null on your system. For example on my pc : env | grep 'DBUS' DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-LBH62GEE0n,guid=9a6d688b01f27de8383ae11c0000001e
according to this page, it mean that dbus daemon is not launched. http://linux.die.net/man/1/dbus-launch
Olivier, the DBUS failure is only emitting a warning, so Banshee should be able to start anyway. I'll test turning off DBUS on my machine soon to see if I can reproduce the bug this way.
(In reply to comment #12) > I'll test turning off DBUS on my machine soon to see if I can reproduce the bug > this way. I tested this by doing DBUS_SESSION_BUS_ADDRESS=foo make run , and Banshee still works for me...
I applied a similar fix to the one for bug 624976: http://git.gnome.org/browse/hyena/commit/?id=20ef00dae30cfe1d8edc6cb4c6f13ece5df015e8 . Hopefully it will make the bug go away as it did in that case (if it doesn't, please reopen the bug!). This problem has been fixed in the development version. The fix will be available in the next major software release (2.5.1). Thank you for your bug report.
