Description Olivier Thomann

2010-07-06 10:48:52 EDT

Using I20100705-1022, I got the following NPE when I tried to switch from the normal console to the java stack trace console and back to the normal console.

Now I am stuck with the java stack trace console and I cannot move back to the normal console.

This one is covered by bug 304863. I haven't figured out that one yet.
