Recent Transmission versions will crash with assertion failure on my set of torrents.

[pathetic_loser]

After running for some time, usually about 5-20 minutes with my set of torrents, recent Transmission versions will crash with following message:

transmission-gtk: peer-msgs.c:708: tr_peerMsgsCalculateActive: Assertion `!tr_peerIsSeed (&msgs->peer)' failed.

Needless to say it screws up transmission usage to the hell. Bug appeared between 2.82 which was ok for me and 2.83 or 2.84, which are not ok anymore. Since 2.84 got some security fix, staying at older version is not an option any more. Unfortunately I can't use 2.84 due to mentioned crashes.

Backtraces:

1. Crash under GDB:

   transmission-gtk: peer-msgs.c:708: tr_peerMsgsCalculateActive: Assertion `!tr_peerIsSeed (&msgs->peer)' failed.
