Bug#635740: linphone: segfaults at startup

Package: linphone
Version: 3.4.3-2
Severity: important

When I start linphone (without a config file, or with one) I see a
window displayed for a very short while and the program crashes
immediately with a segfault.

I seem to get the same exactly error from the version in Testing
(3.3.0).

Backtrack:
