Installed from:    Debian testing/unstable Packages

Text wrapping in task bar entries is not correct.  The first line of text wraps correctly, but all subsequent lines only have one word on them.  For example, the application with the name "Qt Assistant by Trolltech - QTimeLine Class" is rendered in my task bar as:

Qt Assistant by Trolltech
QTimeLine
Class

Another example, an app with the title "Rodrigo y Gabriela - Stairway to Heaven" (a music player) is rendered in the task bar as:

Rodrigo y Gabriela - 
Stairway
to
Heaven

Except the Heaven is not actually visible since it is cut off.
