Bug 279719

Summary: plasma crash after closing amarok that caused many 'file transfers' as jobs
Product: [Plasma] plasma4 Reporter: foggydude <rogier>
Component: generalAssignee: Plasma Bugs List <plasma-bugs>

Severity: crash

Description foggydude 2011-08-09 09:41:19 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
doing several things, while playing amarok

- Unusual behavior I noticed:
this happens sometimes/regularly. on both my machines:
- when playing music in amarok, many popups of 'compleetd file transfer' in the plasma notification area (with no more information, only plasma icon)
- upto 16 tasks shown
- causing slowing down/near freezing of workspace (alt tab, activating launcher, showing desktop, showing dashboard)
- when closing down amarok (alt-q, right clik on icon no or too slow response), plasma crashes
- when plasma restarts, no longer weird 'file transfers'
- on restart amarok, it might tak every long (days) before it comes back

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
