Description Mikko C. 2009-04-27 20:27:44 UTC

Version:           2.1-SVN (using 4.2.70 (KDE 4.2.70 (KDE 4.3 >= 20090415)), Gentoo)
Compiler:          x86_64-pc-linux-gnu-gcc
OS:                Linux (x86_64) release 2.6.30-rc3

100% reproducible here - using trunk.
Steps to reproduce:

1) A media device must be plugged in and have some songs on it. It happens with my MTP, don't know about Ipods.
2) Sort the Collection Browser by: Genre / Artist.
3) Type something in the search bar.
4) Click the Media device to expand it -> crash


About 2). The crash doesn't happen if "Artist / Album" is chosen. Genre seems to trigger this crash.
