Merge misc regression fixes that seem to have fallen through the cracks

Thorsten continues to track regressions, and reporting on known issues
with fixes that don't seem to make any progress.

I'm going to do an rc3 release later today - let's not keep these known
issues pending for yet another rc for no obvious reason.
