[Linphone-developers] Linphone crash and patch for nullpointer in linphone_core_media_description_contains_video_stream

[Stian Hvatum]

Hello,
during a call with latest Linphone from git 
(053fd46975de0cdbfd60055dd3bf3a73177d531b) I received the following from 
GDB. I have compiled linphone without video-support. The attached patch 
seems to fix the problem. Are the mailing list the correct place to 
report bugs and submit patches?

Program received signal SIGSEGV, Segmentation fault.
