[fedora-arm] XFCE4 Task Manager problems on Fedora 17 ARM

[Vasant]

Hi,

I am running Fedora 17 XFCE distribution on Mele A1000 board. Fedora 17 
runs very well on this system.
However when I try running the task manager. I  repeatedly get the 
following message:

(xfce4-taskmanager:1065): Pango-WARNING **: Invalid UTF-8 string passed 
to pango_layout_set_text()

Am I missing some other package ? Any help is appreciated.

Thanks
Vasant
