amarok crashes when using scroll button in dynamic playlist
Hi all,
I'm running Squeeze and I've experienced some (for me) reproducible crashes
with Amaraok. I was wondering if someone can confirm the following before I
report a bug.
Open Amarok
Go to Playlists > Dynamic Playlists
Add a field for Proportional Bias
Hover over the selection field
use the scroll button of your mouse (very) quickly
Amarok crashes with the following info:
Application: Amarok (amarok), signal: Segmentation fault
