Comment 9 for bug 281622

Same (I think) here, with uvccapture.

Each shot prints on log/messages:

kernel [48639.690287] uvccapture[4421]: segfault at 0 ip 00007f81db679f72 sp 00007fffe3d84ea0 error 4 in libc-2.8.90.so[7f81db5d1000+169000]

etc.

But uvccapture is running fine:
> gdb uvccapture
(gdb) set args -m
(gdb) run
Starting program: /usr/bin/uvccapture -m
(no debugging symbols found)
(no debugging symbols found)

Program exited normally.
