Status changed to 'Confirmed' because the bug affects multiple users.

[Alex Bufniță (bubolex)]

Thus bug occured when transmission was closing and sending data to trackers.
I am runing Ubuntu 13.04.

[Jackson Doak (noskcaj)]

Still occurs in xubuntu 13.10

[Unixuser (unixuser)]

Still occurs in Ubuntu 15.04. Dut as I see- who cares?

[John Markh (dragonsol)]

For me, Transmission crashed when I have opened and immediately closed the application (with some active torrents).

[Sebastien Bacher (seb128)]

upstream report seems similar https://trac.transmissionbt.com/ticket/5891

[tikend (metodrybar)]

Appeared on 16.04 alpha 2. Didn't have this bug before, so some update or change triggered it.

[Mateusz Stachowski (stachowski-mateusz)]

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.
