gdb output of backtrace full - missing debuginfos?
This is the backtrace given by gdb by cheese and gnome-control-center when trying to turn on the webcam to take a photo. I'm not sure what debuginfos are missing and I see no prompt to download them.
I'm suspicious that this may be related to kernel problems, and I'm trying to rebuild the rawhide kernel to see how it works. (I have heard it corrects at least one of the issues present on 3.17.x.) The only common thread seems to be libjpeg.
Whatever the cause, this issue appears to be resolved on my machine now.
