D’oh!  Now we have a bug to chew.  (Sorry if this was obvious to you
from the start; it wasn’t to me!)

I don’t know, should we start by having a proper bug report for this and
study how this happen?

Again I’m sorry if I’m slow to understand, but I’d like to make sure we
have a good understanding of the problem before we start discussing
solutions.

Thanks,
Ludo’.
