Apologies, since after reading the other bug report more thoroughly, I
understood that a fix for that issue has actually already been commited to
the devel branch at this point, and indeed, I can also not reproduce my
issue on the latest snapshot. So it looks like this has already been
addressed.
Therefore, ignore my previous email and consider this solved.
Regards,
