Bug 257117

Application: amarok (2.3.1)
KDE Platform Version: 4.4.5 (KDE 4.4.5) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.35-gentoo-r4 i686
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I find that Amarok crashes when attempting to update Podcasts.

I have 13 podcasts. If I start Amarok and leave it, doing nothing at all, it will crash eventually.

If I go to the Media>Podcasts and click 'Update All', it will crash within approximately 20 seconds, every time.

Multiple background tasks are supposedly running, but during this time, the 'green up arrow' on the tasks progress bar (bottom right) does nothing nor does the progress bar move from 0%.
I am running on Gentoo, Intel CPU, 32 bit,, so have built the following packages with -g to assist in diagnosis
* Amarok-2.3.1-r2
* kdelibs-4.4.5
* xine-lib-1.1.18.1
* glibc-2.11.2-r3

Linux lyalls-pc 2.6.35-gentoo-r4 #1 SMP PREEMPT Tue Aug 31 21:28:27 CST 2010 i686 Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz GenuineIntel GNU/Linux



The crash can be reproduced every time.
