Package: ekiga
Version: 2.0.12-1+nmu1
Severity: important
There has been a recent regression in the package which I can't pin
down, which has caused ekiga to hang upon trying to access the v4l2
capable uvcvideo device. It was working about a month or maybe 2,
ago. Now, the echo test to 500 at ekiga.net only works if I disable
video prior to opening the call. If video is enabled, the call
doesn't ever get sent out, and as soon as I try to disconnect the
attempted call, ekiga hangs. It also locks up at various other
points, for instance in the configuration druid, if I select the v4l2
device, it says "Failed to open the device; Could not open the chosen
channel with the chosen video format.", but then will lock up when the
druid is closed.
This is with libpt-1.10.10-plugins-v4l2 version 1.10.10-2
Backtrace follows.
