I can confirm this too. Ekiga crashes when you try to dial without typing a number (the input box says "sip:" only). This is completely reproducible.

I've debugged this issue and it occurs when there are no valid accounts. It has already been solved upstream:
and will be in the next Ekiga release after 3.2.0

TEST CASE: Open ekiga with no valid accounts (e.g. and account that fails to connect) and click dial
Upstream patch is:
This problem can affect new users who are trying ekiga for the first time. The risk is low as it only adds an additional check for a non-zero list before accessing the first element.

This is really borderline for SRU, but it's a trivial and obvious fix, so let's get it in.

Robert, please don't do such non-serious SRUs any more, we should rather concentrate on Karmic now.

No need to upload to Karmic, I'll copy the jaunty-proposed package once it has built.

Accepted ekiga into jaunty-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See for documentation how to enable and use -proposed. Thank you in advance!

I've managed to reproduce the crash with ekiga 3.2.0-0ubuntu1, it indeed crash after clicking dial with no valid account. After updating to the proposed package 3.2.0-0ubuntu2 , tried to reproduce the same, it doesn't crash anymore, the bug is fixed, thanks all.
