Crash in krandrtray

[Andras Mantia]

Hi,

 It seems that krandrtray doesn't like my openSUSE 10.2 system with self 
compiled KDE from 3.5 branch and the NVIDIA binary driver with TV-Out 
(using Xinerama) enabled. As soon as I click on the icon, it crashes. 
The backtrace is:
Using host libthread_db library "/lib64/libthread_db.so.1".
[Thread debugging using libthread_db enabled]

The problematic line is currentScreen() returning 0. Any idea why this 
happens and how can it be avoided?
