The KGet in kdenetwork 3.3 RC2 suffers from the same random crashing problem. However it appears to be linked to the auto save file list function: To reproduce: 1. start kget 2. Right click its tray icon and select 'Configure Kget 3. On the automation tab, select 'Autosave file list every' and set to 1min 4. Click ok 5. Select some items to download, wait one minute and the kget tray icon and main window will disappear Workaround: Turn off Autosave filelist
Having the same problem with 3.3.0 beta 2. Crash also occurs when you manually choose Transfer File List from the file menu (if there are downloads queued).
