Bug 276777

Application: ktorrent (4.2dev)
KDE Platform Version: 4.6.3 (4.6.3) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 2.6.38-gentoo-r3 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
Try to play several times video while torrent was downloading, so "live play". Video window opened but immediately closed. Memory usage increase every time by 150 MiB, so KTorrent use 850 MiB at the end.
Use GStreamer Phonon backend - 4.5.1.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Aborted
