#5777: Segfault in libpurple/blist.c:purple_chat_get_name()
---------------------------+------------------------------------------------
 Reporter:  BigBrownChunx  |       Type:  defect
   Status:  new            |   Priority:  minor

---------------------------+------------------------------------------------
 The function purple_chat_get_name() in blist.c:2090 does not check if the
 prpl_info for a protocol has the function chat_info set to something other
 than NULL, which causes crashes in Pidgin if you hover over the chat
 window name.
