[Ekiga-devel-list] Ekiga - crash on exit

[Jan Schampera <jan schampera web de>]

Hi.

I experimented a bit with an Asterisk server here, and Ekiga (CVS, also
PWlib and OPAL are CVS) crashes sometimes (no idea!) on exit. Attached
is the gdb output of a catched crash. The first few lines are the crash
message, then a normal bt, then all threads backtraced.

HTH
