Comment 5 Hans de Goede 2010-11-17 09:41:28 UTC 
Hi,

Thanks for the bug report.

The problem is that xawtv uses an idle callback to exit when a user requests it to exit, when xawtv is blocked waiting for a video frame from a stuck video device, the user can try to quit multiple times, which will lead to ExitCB getting called multiple times, which leads to the double free errors which have been reported.

I'm currently preparing an update which changes xawtv's exit code from being called multiple times while waiting for a stuck video device.

Regards,

Hans
