Package: transmission-daemon
Version: 2.82-1.1
Severity: important

Hi,

I've been suffering frequent segfaults in transmission-daemon recently,
usually when adding new torrent files or soon after. Crash log says:

transmission-da[14287]: segfault at 0 ip b70f4802 sp b58fedf0 error 4 in
libgnutls.so.28.30.5[b706c000+10c000]

And the program keeps crashing everytime I restart it. The only solution is
to find the offending torrent file, remove it from the download list and
restart the program.

A little trial and error led me to think that the problem is in one of the
trackers referred in those torrent files, maybe a malformed response from
the server or an unhandled error in the communication. Removing those
trackers from the .torrent file seems to solve the problem, but as it's not
a trivial task I guess there's a need to debug the actual problem and make
tranmission handle the error, maybe just ignore those offending trackers.

With the downloads I have running at the moment, I needed to remove two
trackers to avoid the segfault:

*.sumotracker.com: my ISP resolves this server to 127.0.0.2, so I guess
there may be a 404 error or a dropped connection

*.thepiratebay.org: This server resolves to a valid IP (194.71.107.50) but
seems to be down, unresponding or blocked by ISP


Possibly this bug affects upstream, and may be related to other segfault
reports.
