Description Andrew Overholt

2010-06-07 09:19:44 EDT

I installed a clean RC4 SDK and then installed the latest Linux Tools build ().  I then re-started with an existing workspace and I get the stack trace below when trying to enter a ChangeLog entry.  I can also reproduce with a clean workspace.

Comment 1 Andrew Overholt

This looks like another issue with an unclean state or something.  I don't know how this happens but it's something we should investigate if we can reproduce it.

Andrew, is this bug still valid?
I didn't manage to reproduce such NPE.

No longer occurring AFAICT.
