Subject: [Ekiga-devel-list] svn ekiga hangs
Date: Mon, 10 Dec 2007 00:35:52 +0000
Ekiga r5776 is locking up on me very frequently, usually within a minute
of use. I've looked at a few backtraces and they all match the below.
Using the druid or settings dialogues seems to make it crash quicker,
but is not necessary. Looks like deadlock, there's no cpu usage.

Cheers,

Martin.
