Application: kget (2.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.2.1-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

I was in the process of downloading several files, I accidentally started redownloading some of them using http, when I meant to use a bittorrent link.  Several replace file dialogs appeared.  Upon cancelling the first one, KGet crashed with this backtrace.

Other things to note:

I also had several torrents running in the background.  They seemed to significantly slow down KGet for no known reason, and made dealing with the dialogs slow.  I don't know if that triggered some obscure timing bug.

-- Backtrace:
Application: KGet (kget), signal: Segmentation fault
