Please, Boris
I know you have answered this question before, but please be a little more forthcoming!
From what I gather you've had a field day up till now, so don't spoil it by getting unduly annoyed at the end. You're probably just tired.
The answer to the question:
Look in the Bug Tracker.
Item 12 deals with this problem in depth.
Editing:
And oh, I forgot - The fix for this bug is already rolled into version 6.01-01 - try that instead of the one you are using (probably 6b3).
