And if you disable video preview and video in calls, ekiga works? I ask because the crash doesn't look related to a video issue...

I have no idea. I don't know how to do that, but if you can tell me I'll try.

You can enable/disable video preview from the main window ; there's an icon for this.

You can enable/disable video in calls using the preferences window (codecs->video codecs->enable video support).

You could also run the video test in the druid.

I'm really not convinced it's a video-related crash.

I have no idea if it is or if it isn't. Thing is, I can't even start it. I click ekiga softfoon, then nothing happens for about ten seconds, then a error report is being made. I'm a beginner at this, I try things without being sure it won't crash my system. In the beginning of using ubuntu I had to reinstall it three times, because I broke it. I don't even know what the druid is. 

So, do you have other things I can try? (And please, idiot-version instructions)

Aaaaahhh!!!!! So I was right : nothing to do with your webcam at all!

Ok, so this is a crash-on-startup.

So let's go with the easy questions : how did you install ekiga ? From your distribution's servers, from binary packages downloaded from somewhere else, from sources ?

With synaptic

Could you tell us the dependancies of the ekiga package ? (paste us the output of the command "apt-cache show ekiga" run in a terminal)

Of course

*** Bug 417345 has been marked as a duplicate of this bug. ***

I don't understand the backtrace ...

I must admit that seeing gmcontact_delete after calls to PPluginServiceDescriptor::~PPluginServiceDescriptor is definitely weird.

Corrupted stack ?

Yes, most likely a corrupted stack, also regarding the other backtraces. Weird.

J.

Is there a way I can try to fix it?

Can you find packages with debug symbols, install them, and try reproducing the bug ?

Reproducing the bug is simple: click Ekiga softfoon and it crashes. I can't find any debug packages.

I tried deinstalling camorama (the last program I installed before Ekiga crashed). Didn't work: Ekiga still crashed.

I tried deinstalling ekiga completely through synaptic and then installing it from source. Here I ran into quite a few problems. I followed the instructions on this: http://www.cutlersoftware.com/ubuntuinstall/#source site, and got when I tried to do 'sudo make install' the following:

Ekiga (I didn't get further than ./configure): (lots of checking text, let me know if you want to read that too) 
error: Package requirements (gtk+-2.0 >= 2.6.0 gthread-2.0 >= 2.4.0 esound >= 0.2.28 gconf-2.0 >= 2.2.0 libgnome-2.0 >= 2.2.0 libgnomeui-2.0 >= 2.2.0) were not met:

No package 'libgnome-2.0' found
No package 'libgnomeui-2.0' found
 

Please keep away from the code since you obviously don't know enough to handle it...

I know that, and you're not helping. Do you happen to have a useful suggestion?

I am helping whenever I post to your bug report.

A useful suggestion was made by Damien and was : "look for debug packages".

I have another useful suggestion : 2.0.7 is out, you should upgrade to it, since it contains a few bugfixes and security fixes.

It looks like a broken upgrade to me if it crashes directly when starting. Something corrupted in the libraries ?

I can't upgrade to 2.0.7 yet, it's not on synaptic and as Snark pointed out, I should keep away from the code.

Assuming something is corrupted in the libraries, how do I fix it?

Hmmm... this problem has been fixed long ago : I don't know why this wasn't marked as fixed already!
