Description Fabio Zadrozny CLA 2013-02-28 19:23:06 EST 
I can't reproduce this reliably, but it happened a few times for me already.

I'm posting the stack trace below:

In which editor does it happen?
Comment 2 Fabio Zadrozny CLA 2013-03-01 07:52:41 EST 
It happened in the PyDev editor (I'm its author and I'm testing it against the latest Eclipse 4.3).

From the stack trace I couldn't find anything really related to the editor (that's why I'm reporting it against Eclipse itself) -- also, I didn't experience this issue in the latest 3.8 version (so, it appears something introduced in the 4.x branch).
Comment 3 Dani Megert CLA 2013-03-11 07:31:12 EDT 
I cannot reproduce this in any of "our" editors. If you still see this, then please provide a test case/plug-in that allows to reproduce and investigate the issue.
