Comment 7 for bug 968186

This stack trace makes little sense. In do_mount(), we see that the gphoto2_backend is initialized:

       gphoto2_backend = 0x9930e0

A few lines before release_device (gphoto2_backend) it even dereferences gphoto2_backend->camera, and that did not give a segfault, so at that point gphoto2_backend was still valid. But at this call, the stack trace claims

#2 0x00000000004058c5 in release_device (gphoto2_backend=0x0) at gvfsbackendgphoto2.c:621

This cannot be true, before line 621 release_device() derefs gphoto2_backend dozens of times. So that 0x0 is wrong.
