4.5 crashing on startup on mac os x

It's most probably config folder (usually located at
~/Library/Preferences/IntelliJ IDEA) has corrupted config XML files.

I tried the following:
-deleting the whole directory ~/Library/Preferences/IntelliJ IDEA
-deleting all the xml files in ~/Library/Preferences/IntelliJ IDEA
-deleting just the xml files that looked to be generated by my prefrences

but I still get the same errors as before with IntelliJ 4.5 and 4.0. (although 3.0.5 does run)


>>with IntelliJ 4.5 I still get:

...I also had to delete ~/Library/Caches/IntelliJ IDEA

Thanks so much for your help!

The same thing happened to me on Windows too.
I figured out the following file: %IDEA_HOME%/system/plugins/action.script was currupted. I just deleted it. I didn't have to re-install IDEA.
