David, this is a blocker for the 2.10.3 release :)

Cheers,

comment:2

Okay, it is a blocker, but some of the failures possibly are from patches
new to 2.10.3.rc0. Should I wait for 2.10.3.rc1 or try to fix it now?

BTW, I would dearly love to include a new example based on the recent patches of
Simon King. Would that be okay?

comment:4

I assume that there errors have not changed from rc0 to rc3?
