Description rookcifer 2009-05-07 17:00:56 UTC 
Version:           2.0.90 (SVN) (using KDE 4.2.2)
Compiler:          gcc (GCC) 4.3.2 20081105 (Red Hat 4.3.2-7) 
OS:                Linux
Installed from:    Fedora RPMs

When I added more than one applet to the center panel I got a crash.  To be more specific, I was actually using the arrow to move the applet panels from left to right when the crash occurred (the arrow where you can move one applet left or right, etc).  I did not have any extra plugins loaded.

I was able to reproduce this a second time by putting two applets side by side and then using the arrow to move them around in random motion.  Eventually, Amarok gave a SIGSEGV and crashed again.  On the second crash the two applets I was "moving around" were the "current track" and the "albums" applets.

I was able to get a backtrace on both crashes.  This is my first bug report, so I apologize if I left any pertinent info out.

System info:

Fedora 10 x86_64
KDE 4.2.2
Amarok 2.0.90 (Beta) compiled from source downloaded from the Amarok site (with debugging enabled at compile time)
GCC 4.3.2

Comment 1 Simon ESNEAULT 2009-06-16 01:11:12 UTC 
Leo, was this solved for 2.1 ?

-Simon
Comment 2 Leo Franchi 2009-06-18 22:08:06 UTC 
closing as the 2.0 containment is ancient history by now
Comment 3 Myriam Schweingruber 2010-01-21 20:04:49 UTC 
*** Bug 223586 has been marked as a duplicate of this bug. ***
Comment 4 Myriam Schweingruber 2010-01-21 20:05:57 UTC 
Reopening based on duplicate in comment #3: the backtrace is absolutely identical, but with Amarok 2.2.2 :(
Comment 5 Mark Kretschmann 2010-01-30 14:41:49 UTC 
commit a58b0e767fe5930f60ead457622c570b4c98a5cf
Author: Mark Kretschmann <kretschmann@kde.org>

    Try to fix bizarre crash with moving applets.
    
    Leo, could you double-check this commit please? Just to make sure that I
    didn't do something stupid.
