[GnomeMeeting-devel-list] Segmentation fault on exit

[Hannes Ebner <dev stdout at>]

Hi,

I recently upgraded to the latest version of Ekiga (package
gnomemeeting-cvs version <1.99.0-20060113> on Debian Sarge) and I get a
SIGSEGV every time I quit the application. I attached a bt to this mail.

I noticed another problem: I'm using several SIP accounts, while playing
around I tried to register/unregister a couple of times. Once (or
twice?) I got the message that a mutex could not be destroyed. I could
not reproduce it so far.

Regards,
Hannes
