Hi,

I got this npe, while I installed the texlipse plugin via p2. Even if the plugin
is designed for an older version of eclipse (I successfully installed/used
via update manager in 3.4M5 though), that shouldn't happen I guess.

Hi Felix,

Please try this with M7 which should be declared today and among other
things should handle the problems you're seeing.
1) the NPE should now be trapped so at the very least if there is a genuine
problem a proper error message will be logged and returned.
2) Support for old style plugins is now in place so if it worked in old UM
it should now also work with p2.
