No, I just couldn't find time during all that bug fixing :)

Sorry for the delay, going to take a look after the eastern holiday here.

Christian.

The message is just for history. The issue was fixed between
b253435746d9a4a and 5.18rc4.

We have implemented a workaround, but still don't know the exact root cause.

If anybody wants to look into this it would be rather helpful to be able to reproduce the issue.

Regards,
Christian.
