Hi,

Can you try this package to check if this bug is fixed upstream?

https://launchpad.net/~sevmek/+archive/ekiga-stable-prerelease

Best regards,
Yannick

[Matt Lavin (matt-lavin)]

The behavior is much better using the pre-release version. I still get
random crashes and deadlocks, but it's much less frequent.

Matt Lavin ,

Please report remaining issues like crash or deadlock upstream:
http://bugzilla.gnome.org/enter_bug.cgi?product=ekiga

We are in the process to fix them.
Here is our current knowledge about issues with this version of ekiga:
http://wiki.ekiga.org/index.php/Pre-release_test#Ekiga_3.2.6_Pre-tests

Here is a how-to produce a backtrace in case of crash or deadlock (please install the package "ekiga-dbg" first):
http://wiki.ekiga.org/index.php/Debugging_Ekiga#Getting_the_stack_backtrace

Best regards,
Yannick

[Yannick Defais (sevmek)]

Hi,

Ekiga 3.2.6 was released yesterday. It fix numerous issues. Could you please give it a try to check if it solves your issue?

https://launchpad.net/~sevmek/+archive/ekiga-released
(instructions and packages)

Best regards,
Yannick

Hi,

the upgrade to ekiga 3.2.6 solved my problems with deadlock on hangup.

Best,
Jakub

[Jakub Z (zakrzewski-jakub)]

Unfortunately the problems with deadlock showed up again. My current version of ekiga is 3.2.6 and there is a problem when I'm connected using VOIP. If the connection takes more then 10 second, the application is locked and no operations like menu operations or clicking the "hangup" button are possible. I did 'sudo apt-get purge ekiga' and 'sudo apt-get install ekiga' but I hasn't helped.

[Manolinux (mu)]

I had the same problem. I used the sevmek to update to 3.2.6 (and checked the version).

The program still freezes on hangup, just as mainstream package did.

It seems that it asks for the sound system to close, but waits forever.

[Eugen Dedu (eugen-dedu)]

Please use ekiga 4.0.0, it fixes such issues.
