Created attachment 159870 [details] Ktorrent backtrace in locked up state. SUMMARY Sometimes, as Ktorrent is seeding a number of torrents in the background, it locks up and stops uploading and downloading torrents. If you click or double-click on the Ktorrent icon in the system tray, nothing happens for about a minute, and then Ktorrent context menu opens (with set upload/download limits, suspend torrents, etc.). The context menu is animated, I can pick options or close it by clicking away, but the main Ktorrent window cannot be opened. For example, picking "Configure Ktorrent" does nothing. STEPS TO REPRODUCE I do not have a reproducer, it just happens at random points sometimes (not very often, maybe once a month). System uptime doesn't seem to matter, it can happen after a day or a week of uptime. I have a few dozens of downloaded torrents that are seeding. I think I also saw it happen also when I had one or a few torrents downloading.
