GNOME Bugzilla – Bug 395813
GnomeCD crashes unless CD Drive is already in use
Last modified: 2007-01-12 16:11:36 UTC
I haven't run GnomeCD for sometime now. Recently when I did try to use it, I noticed that the "Starting CD Player" notification would show up in the GnomePanel, but subsequently GnomeCD wouldn't startup. Neither would BugBuddy pop-up with a failure - hence I don't have a BugBuddy Stack Trace in this Bug. The next best thing I did was get an strace output - which I'll attach to this Bug presently. Other tools (like SoundJuicer) open up correctly and can play my CDs. GnomeCD used to work correctly on my system, but I have no recollection of whether I've used it successfully with Fedora Core 6. I'm running Fedora Core 6 with GNOME 2.16.0, gnome-media-2.16.1-2.fc6. The only way I have been able to get GnomeCD up is by first cranking up SoundJuicer and playing a track (so that my CD drive is busy). Next, start GnomeCD - which pops up a blank/empty GnomeCD window (title: CD Player) and remains blank/empty until I quit SoundJuicer. The moment SoundJuicer quits, the GnomeCD window gets all its buttons and labels. It says 'No Disc' but lists all the tracks from the CD in the TrackList and is able to play them too. The same blank/empty GnomeCD window can be seen if any further instances of GnomeCD are started provided one of them is already up. Starting GnomeCD all by itself - or with SoundJuicer present (but not playing anything) causes it to 'crash' for which the strace is attached.
Created attachment 80114 [details] strace output for the GnomeCD crash
Strace is not very useful, please attach a gdb backtrace, or at the very least the commandline output, instead.
Finally, here is the backtrace that I obtained from GDB. Hope this is more useful than the strace. $ gdb gnome-cd GNU gdb Red Hat Linux (6.5-15.fc6rh) Copyright (C) 2006 Free Software Foundation, Inc.

Here is an expanded section of the top of the function stack after I just installed cdparanoia-debuginfo. In case more info is needed I'll be glad to provide it. ---- Program received signal SIGSEGV, Segmentation fault.

Looks like a crash inside the cdparanoia code called by the gst element -> reassigning.
