Build: NetBeans IDE Dev (Build 20081213040647)

OS: Linux, 2.6.27-ARCH, i386

User Comments:
graydsl: I deleted an older Python Platform in the Python Platform window. And since then (~ #290) I was not able to run a Python script. Because if I try to change the Python Platform in Project Preferences or for NB a NPE happens.

This is still a problem in #401. I don't know if it only happens on Linux but this should be considered as a severe bug.
If there is a workaround or something, an email would be nice. In #401 it's possible to change the Python Plattform for
a project but the Tools->Python Platforms gives the NPE above.

After deleting /home/user/.netbeans/dev the platform dialog works fine.
Comment 4 Peter Lam 2008-12-24 01:21:54 UTC 
verified in build #435. no longer reproducible. Yes, I started from a fresh userdir.
