Picked up my old buckminster investigations and run into a problem that i have no idea on how to solve.

I build an eclipse product, with feature etc as set up in the buckybook (build an rcp app) strange thing i have done this before and suceeded but now it just halts when trying to create an site/clean (in ui) or what ever with the same problem. in ant debug i get:

[ant] Setting ro project property: user_homedir -> null

java.lang.NullPointerException

no idea why this is happening. buckminster core says 1.3.1.r11570 (latest on updatesite)

In my case this error was created by using googles' Workspace Mechanic
and Buckminster in one Eclipse Installation.

This bug is fixed (https://bugs.eclipse.org/bugs/show_bug.cgi?id=320586)
