I'm not sure how to address this problem, I never encountered the
problem myself, not on Debian since squeeze and not on any other
distribution.

Can you reproduce this on other systems and explain any changes you did
to XML configuration or from the user side?

I really doubt that this is a major problem, and if it can be
reproduced only 

So far, sorry for the late answer...
