While smoke testing WTP http://build.eclipse.org/webtools/committers/wtp-R3.1-I/20090108074838/I-3.1-20090108074838/ I have installed S-3.5M4-200812111908/eclipse-SDK-3.5M4-win32.zip. When I start the installation the Welcome view contains an error. The archive was extracted in a new folder. No previous installation in the folder.

I have reproduced the error by extracting all the archives again.
We're getting the same error when executing PDT unit tests...
This is a pretty old bug, but I think ok now? I'll marked as "works for me" instead of "fixed" since I don't know what specifically was done. Note, the "welcome page" stuff was just replaced in M6 RC1.
