Bug 189021

Version:           trunk (using Devel)
OS:                Linux
Installed from:    Compiled sources

When pressing Delete in Amarok once after all the tracks in the playlist were selected, then the playlist is cleared. Pressing delete again causes Amarok to crash. I get the following error on the console:

{{{{
ASSERT: "!isEmpty()" in file /usr/lib/qt4/include/QtCore/qlist.h, line 252
KCrash: Application 'amarok' crashing...
sock_file=/home/shlomi/.kde4/socket-telaviv1.shlomifish.org/kdeinit4__0
}}}}

And KCrash reports:
