This looks like bug 204070 or bug 207177. 
- Could you check them ?
Thanks

Comment 2 qqqqqqqqq9 2009-12-14 20:22:42 UTC

might well be the same bug, although they don't mention the message about the repositioning.

Comment 3 Dario Andres 2009-12-14 20:47:09 UTC

I just checked and I have the same output when trying to reproduce the steps of bug 207177, so it is likely to be the same.
(Note that this debug output will not appear on all the setups , as it is disabled by default)

- Do you have a similar configuration as the stated in bug 207177 comment 5 ?
Thanks
