transmission crashes due to SIGPIPE when adding torrents via web interface

[b]

Binary package hint: transmission

Often when I add a torrent using the transmission web interface transmission will crash. Usually the torrent does actually get added since when I restart it appears. Sometimes the crash happens before the torrent is added. This does not happen all the time, but does happen regularly, and always after adding a torrent via the web interface.

I did not see transmission-dbg, transmission-common-dbg or transmission-gtk-dbg packages. Here is the GDB backtrace:

Program received signal SIGPIPE, Broken pipe.

Package transmission not installed and no hook available, ignoring

I can't seem to change this bug to effect transmission-gtk or transmission-common (only "transmission" is an available choice).

there are instructions on how to get -dbgsym packges here: https://wiki.ubuntu.com/DebuggingProgramCrash

Also I see you asked upstream for a .deb of a newer version, installing the packages from maverick should work: http://packages.ubuntu.com/maverick/transmission (you will need to install -common, then -gtk)

This is happening because of gdb, not because of Transmission. This isn't the cause of the crash. See this for information on making gdb play nice with SIGPIPE: http://ahlamnote.blogspot.com/2006/12/gdb-ignore-sigpipe.html

Even once you get SIGPIPE handled, it looks like you ran gdb on a stripped version of the program, as most of the useful debugging information has been replaced with "??"... so if you have to go the gdb route, you'll need a dbg version of transmission.

Anyway, a crash report generated by Ubuntu will greatly help us in tracking down your problem. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. Thanks!

Thanks,

I found the tranmission-gtk-dbgsym package so I'll install then when my
current transmission session is over.

Thanks for the sigpipe hint.

I've been running transmission in GDB for a while now and transmission
has not crashed since. I guess it was a fluke, maybe with updates
installed in background while transmission was running.

I'll keep an eye on it, but it indeed appears invalid.

Closing as invalid based on comment #5 from OP
