after removing the builddirs and rebuilding I don't get the constant error
messages about broken repositories.

However kdev4 still asserts during shutdown, but at a different place now:

I can't say I like having to erase the builddir, it shows that cmake
doesn't get its dependencies right - sometimes. OTOH this might be related
to the problems with the krosswrappers, because building kdevplatform fails
when changing API that kross wraps and the only way out of the "circle" is
by ignoring errors when building kdevplatform, then building kdevelop and
then re-generating the wrappers. Anyway, thats a different thing and I'll
talk to Aleix about that.
