xfce4 places plugin

[dynnamitt]

The xfce4-places-plugin is not opening my Preferred FileManager (PCManFM) ..it keeps opening Thunar
This is strange since Sabayon is using version 1.2 that has a bugfix #4463 (saying that this is now fixed)

I have tested "exo-open" in the shell and it is opening PCManFM,
The AppMenu is also doing this right.
