Description Peter Larsen

Build Identifier: M20110909-1335

I found this in my log. There are 2 stacktraces which occurred nearly at the same time, so I assume the second is a result of the first. The second looks like bug #349543.

Moving to Platform/UI.

It seems you were trying to use Alt+Left to go back in the editor history, is this correct?

Could very well be as I do that often (alt+left), but I dont know, as I only noticed the errors because I was looking in the .log for other reasons.

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.

If the bug is still relevant, please remove the "stalebug" whiteboard tag.
