Description Olivier Thomann

Using I20091110-0800, I got this exception in the .log file while editing launching configuration.
I don't know exactly what I did when it occurred. Hopefully it will be possible from the stack trace to handle the null case.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
