This looks similar to bug 520762. Any chance you can reproduce this with the gphoto commandline tools (e.g. run 'gphoto2 -L') and other gphoto2 using apps (e.g. f-spot, gthumb)? Thanks.
I got several similar crashers when mounting my camera using the computer location in nautilus, the camera works correctly using gphoto applications, what debug information would be useful there?
It would be useful to try a few other devices. That would help determine whether the bug happens in libgphoto2 or in the vfs daemon. What kind of patches and version does Ubuntu have for libgphoto2? While developing the backend I used four different devices and never seen this. But I'm using Fedora but that shouldn't make any difference. Though if you or others you have access to a Rawhide or other recent distro with this stuff it would be useful to get test reports there too, ideally using the same hardware.
I also get this bug with a Samsung YP-U3. Double click on the player icon crash. flo@flo-laptop:~$ gphoto2 -v gphoto2 2.4.0 Copyright (c) 2000-2006 Lutz Mueller and others gphoto2 comes with NO WARRANTY, to the extent permitted by law.

What is actually the difference between double click and right-click->mount ?
I get the exact same behavior with rawhide : Double-click fail, right-click->mount works. Just for info, 10-camera-libgphoto2.fdi still use the deprecated key info.bus.
The question raised in comment #1 has been answered downstream: I can confirm this bug. I also can confirm that 'gphoto2 -L' works, so this has nothing to do with the sansa issue. I also found that when mounting with right-click->mount it works. Can somebody try that ? I am thus reopening this bug.
The last comment on this bug was nearly a year ago. Please test again with an updated distribution, and provide a new backtrace if the problem still occurs.
There is a similar crash using 1.1.6 on https://bugs.launchpad.net/bugs/335017 "#0 0x00007f353641da2a in pthread_mutex_lock () from /lib/libpthread.so.0

And now, two years later, are there still similar crashes happening?
I don't remember when I last got this.
ticket should be closed
