Comment 1 Vitezslav Stejskal 2007-11-14 11:00:35 UTC 
I'm not sure why we get MultiFileObject$VoidValue instead of String or null when reading a folder attribute. Maybe Radek
would know. I can workaround this in EditorSettingsImpl. In the meantime you should be able to resolve the problem by
using a fresh userdir. Just pass --userdir /path/to/your/new/fresh/userdir on commandline when launching the IDE.
Comment 2 Vitezslav Stejskal 2007-11-15 10:50:00 UTC 
From Anthony Van der Zwan by email:
This bug happens after an clean install off  6.0rc1 (but not when 5.5 is on the same machine...)
