I've just reproduced this situation.

I had an uncaught exception in my GenericSetup script (setuphandlers.py /
postInstall, as generated by ArchGenXML).  The exception _quietly_ fails
the install - but all types are already registered.  I suspect this only
happens because I have commit points in my postInstall.
