Don't take this as bug report, the first ERROR message is right
and I should have noticed what's wrong sooner, but instead I was
checking "ps" for hanging zombie bitbake (which still happends
from time to time).

Is there something we can do for average bitbake user to get clearer
message?

$ bitbake -c cleansstate tracker | bitbake -c build tracker | tee log.tracker

ERROR: Only one copy of bitbake should be run against a build directory
Traceback (most recent call last):
