In the upstream bug report the dev wrote "patch which prevents crashes on session close (at least the ones related to evdns_getaddrinfo_cancel)". So it doesn't look like it covers this case.
Also Fedora users had the same crash in Fedora 21 and 22. Bug reports have been closed because the releases reached EOL. https://bugzilla.redhat.com/show_bug.cgi?id=1161842 https://bugzilla.redhat.com/show_bug.cgi?id=1222699 ** Bug watch added: hacking a member #1161842 https://bugzilla.redhat.com/cgi-bin/bugreport.cgi?bug=1161842 ** Bug watch added: hacking a member #1222699 https://bugzilla.redhat.com/cgi-bin/bugreport.cgi?bug=1222699 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to transmission in Ubuntu. https://bugs.launchpad.net/bugs/1037960 Title: transmission-gtk crashed with SIGSEGV in evdns_cancel_request() Status in transmission package in Ubuntu: Confirmed Bug description: This crash occured while torrents was downloading in progress, but transmission not yet got ended/restarted even after this bug submission...
