Description

I'm tying to use https://github.com/tieto/sipe on Fedora 26 which has:

$ rpm -qa | grep nice  
libnice-devel-0.1.13-8.fc26.x86_64  
libnice-0.1.13-8.fc26.x86_64  
libnice-gstreamer1-0.1.13-8.fc26.x86_64

and getting a [[ https://github.com/tieto/sipe/files/1492935/ThreadStacktrace.txt | segfault ]] where the top 10 frames are:

Is this a known issue that I need a fix for or should 0.1.13 be stable enough to use with pidgin-sipe?

It's very well worth mentioning that the Fedora packaging of 0.1.13 has a [[ http://pkgs.fedoraproject.org/cgit/rpms/libnice.git/tree/libnice-0.1.13-20160610.patch?h=f26 | nice sized patch ]] on it.
