Bug 328581

Application: rekonq (2.4.0)
KDE Platform Version: 4.11.3
Qt Version: 4.8.5
Operating System: Linux 3.11.9-200.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
I was copying a lot of data to a USB disk - all 4 CPU cores at 100% for several minutes. 
Grooveshark (gnash?) can not handle this. 
Normally is hangs  for a second or so, this time it crashed multiple times. 
Try reproducing by doing multiple large copy/move orders simultanious.
