Ahh, great, thx. And sorry, had missed that in the flood of regressions
reports I have to deal with.

Golan Ben Ami: do you maybe have an idea what might cause evgeny's problems?

Evgeny, btw: one way to fix this would be a bisection between 6.3 and
6.4-rc1 to find the change that resolves your problem. But maybe the
developers have an idea that makes this unnecessary.

Ciao, Thorsten
