I'm getting a similar behavior. Ktorrent is repeatedly crashing when removing one or multiple completed torrents (I am not removing the data) from the upload section. On removal of multiple, some get removed while others linger after the application is restarted. On single removals, the torrents are not I am running the latest stable kubuntu (with ktorrent 2.2.0).

The following plugins are enabled:
-Bandwidth Scheduler (not used)
-IP Filter (using http://www.bluetack.co.uk/config/psplist.zip)
-Import
-Info Widget
-Log Viewer
-Scan Folder
-Search
-Statistics
-UPnP
-Web Interface (not used)
-Zeroconf

This has happened on existing and new torrents, but every time.

Here is the backtrace:
