gvfsd-gphoto2 crashed with SIGSEGV in pthread_mutex_lock()

[David Fourer]

Binary package hint: gvfs

I am not qualified to say if this is same as older bugs, ranging from 202304 up to 522944.
I plugged in my camera to usb after upgrade to Lucid and turned on camera. I see that gthumb 2.10.11 is opened automatically, but I get a report (from apport) that gvfsd-gphoto2 has crashed.
Camera is Canon Powershot A1100 IS.
