Application: ktorrent (4.0.3)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
Ktorrent regularly crashes while downloading torrents.  The only thing I can figure that's causing it is the program doesn't wait long enough for the drive setup I have.

I am downloading to a large external USB drive, with a link setup in my home directory.

The crash can be reproduced every time.

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