Spontaneous crash (might be related to queue manager)

kriko Registered Member Posts 164 Karma 0 OS	Spontaneous crash (might be related to queue manager) Sun Jul 18, 2010 11:47 am Seems like ktorrent crashes when I move a single torrent up within queue manager list, but it doesn't happen every time. Is there any way I can improve this bug report?
