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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/968186 Title: gvfsd-gphoto2 crashed with SIGSEGV in __pthread_mutex_destroy() Status in GVFS: Unknown Status in “gvfs” package in Ubuntu: In Progress Status in “gvfs” source package in Precise: In Progress Bug description: I plugged in my Nokia 5800 to import the photos with Shotwell, something I do regularly, and received this bug.
