First of, your code fails here when trying to figure out the systray's depth.
However, the result of that calculation isn't used anyway, so an "#if 0" fixes
this.
The next problem is that awesome registers your systray window as both a regular
client and as a systray window. Skipping the MapWindow request fixes this as
well.
Patch is attached.
Cheers,
Uli
