[Brandon Bolton (brandon-bolton-224)]

This just happened to me when I tried to change the volume in the applet at the top. The keyboard shortcuts work though, just the slider bar locks up my computer.

[Paul Kenyon (rixoff)]

Exactly what Brandon said happened to me. This is just like the last unity-panel-service bug that was apparently fixed. In the past, the slider was not controllable. It would go by itself the rest of the way to the end. Now, I can actually move it just a notch, and drag it to specific points. But after a second of draging it around, it got stuck and crashed again.

So, it looks like the bug is getting narrowed down, but still not completely fixed.
