Soerens original report was a 2.6.25 regression.

And #10377 that was closed as a duplicate of #10117 was also reported as 
a 2.6.25 regression.

#10117 seems to suffer from the common disease of people hijacking an 
existing bug, but Soeren's issue that was what was originally tracked in 
#10117 is (or was) a 2.6.25 regression.

If other people have similar problems that already existed in 2.6.24 
these are different issues that should be tracked in their own bugs.
