This is from the logs:

So it seems that the daemon tried to build them, but they all failed.
Probably at that point the log file weren't created.

I don't really understand why you were able to build
/gnu/store/wgk46pv09m1y8b7iq5fbkhay5hs6hnmr-libcss-0.8.0.drv manually
then.

'starttime == 0 && stoptime != 0' is explained by the fact the exception
(from 'build-derivations&'?) was thrown before 'handle-build-event' was
called (which should have set starttime), and later on
'(update-build-statuses! store batch)' was called, which only sets
stoptime (because the output is invalid).

Any idea?
