Title:
control center crashes when I try to select Logitech BCC950 webcam
sound input
Status in “gnome-control-center” package in Ubuntu:
Confirmed
Bug description:
syslog tells me:
gnome-control-c[6031]: segfault at 7fffe1112ec8 ip 00007fa72cdba9f2
sp 00007fffe1112d90 error 6 in libc-2.15.so[7fa72cd72000+1b5000]
earlier, I got a crash panel that told me I had a vsprintf error, but
now I no longer get the crash panel. (by the way, the bcc950 video
input works just fine.) more detailed syslog.
