Transmission

When I start transmission, after about a miniute it crashes. I ran transmission-daemon in a terminal. Here is the output
astarmathsandphysics@SERVER:~$ transmission-daemon -f

What can I do?

Here is something else from a terminal

Think I didn't cust and paste properly. Try this instead

This is the error I get in logfile

ul 9 23:15:58 SERVER kernel: [90520.087345] transmission-gt[32578]: segfault at 1997c2228 ip 00007f0fcf0e6111 sp 00007f0fbe1377e8 error 4 in libc-2.15.so[7f0fcf05d000+1b5000]

This is for transmission gtk running but not transmission daemon

Jul 9 23:45:44 SERVER kernel: [92305.763850] transmission-gt[550]: segfault at 10d7c2228 ip 00007f8342ecd111 sp 00007f8331f287e8 error 4 in libc-2.15.so[7f8342e44000+1b5000]

What is the difference between transmission gtk and transmission daemon anyway?

I think it is an error in a torrent file. I am running 9200 of 9300 torrents succesfully. Will brave the rest tomorrow.
