Segfault during call setup. Does not always occur. Perhaps 1 in 5 :-(

maybe_retry_call_with_ice_version
SIPE_ICE_DRAFT_6 compatibility is likely buggy, but Sipe shouldn't get into that function in the first place unless some very old version of Lync server is used (I doubt this is the case). There must be something not quite right in the SIP signaling messages. Please post here or send me your pidgin log from before the crash; I'd like to inspect the communication more closely.
