Unfortunately, the patch is ugly as it contains lots of unrelated stuff, but at least it comes from a "stable" branch :-) Submitted to network:telephony project, please accept and forward to FACTORY: 58427 State:new By:seife When:2011-01-16T15:31:33 submit: home:seife:testing/linphone332 -> network:telephony/linphone Descr: - Patch up to current git state of branch 3.3.x. Unfortunately, the git history is not helpful to create a changelog. But this fixes bnc#664808 (linphone segfaults at incoming call). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The problem is that upstream development seems not to be very structured, e.g. git commit history is a mess. I also did not find out what the exact cause is (ok, somehting is obviously NULL or corrupted), and I am not at all familiar with the codebase. So the first try was to check if it is fixed in the latest devel snapshot (it is), and after realizing that this needs updated libexosip and libosip I thought about something less intrusive. Then I checked out the last version of the 3.3.x branch, did a "make dist" and then diffed the contents of the tarball against the 3.3.2 tarball. That's the diff I added to the package which was accepted in network:telephony now. If you check the diff, it contains many small changes coming from the fact that autoconf generates different tarballs depending on the build host. A lot of changes are also to windows only code. But the rest is still too much for me to check which of the changes actually fixes the bug. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
