New install: problem: double launch of applications bug with XFCE and WindowMaker

[Tom Allison <tallison@tacocat.net>]

I don't know how else to explain this, but when I click on a http link 
in thunderbird, two applications of firefox launch trying to read the page.

Now here's where it's a bug

I remove XFCE and it goes away.

Package XFCE4
Version 4.0.5-1
