In what way does it crash? Exceptions, segmentation faults, unresolved symbols? libxxf86dga hasn't had any functional changes, just some protocol header moves. The only thing I can think of is changes caused by compiler changes.

I checked it again today and it crashed with the old libxxf86dga as well. Here is the console output (using the latest libxxf86dga).

I downgraded libv4l (0.6.0-1 -> 0.5.99-1) and xawtv doesn't crash.

Is this still an issue with 0.6.3?

After the latest updates xawtv still crashes when I try to change channel. I run xawtv through gdb. You can read the output in the attachment.

i think libv4l has been replaced by v4l-utils. Maybe replacing libv4l with an upgraded package solves this.

any status updates?

Is this still a problem?
