For all but one of the split package members for each architecture, it will spit out

On branch master
nothing to commit, working directory clean

==> ERROR: An unknown error has occurred. Exiting...
/usr/bin/xbs: line 103: XXXXX User defined signal 1   "$HELPER" release-server "$@" 
==> ERROR cd staging/XXXX//abslibre/XXXX/XXXX/XXXX && xbs release-server XXXX XXXX

The message is harmless, but it should be fixed.

I take full blame, and know what has to happen.
