Application that crashed: ktorrent
Version of the application: 3.3rc1
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31-gentoo-r2 x86_64

What I was doing when the application crashed:
I used "qdbus org.ktorrent.ktorrent /core load" to load several torrents in short succession.

The "where do you want to download to?" dialogs were very slow in appearing and unresponsive once they did.  After finally clicking ok to all of them, KTorrent crashed.

 -- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
