Comment 1 Mark Kretschmann 2008-10-02 23:04:46 UTC 
Was this a random one-off crash, or are you able to reproduce this reliably?
Comment 2 Alex Merry 2008-10-03 22:18:49 UTC 
Sorry, should have said.  It was a one-off thing.
Comment 3 Mark Kretschmann 2008-10-04 01:47:31 UTC 
Well Alex, as we're both coders, I'm simply gonna ask you: What should we do with this report? We could reassign it to kdelibs, or close it and just assume it was a heisenbug ;)

Just keeping it open here in this state is probably not gonna do much good.
Comment 4 Alex Merry 2008-10-07 20:54:29 UTC 
I'm not sure it's worth hunting down a rare race condition in the debugging code.  I suspect it's Amarok's fault, so I don't think it should be transferred, at least not until that possibility has been checked and eliminated.

I'll close it as WONTFIX on the basis it's probably not worth the effort.
