------------------------


"qconf -Aq broken_queue.txt" (see definition file below) prints the error message:
'error: " " is the only character allowed between the attribute name and the
value in line 18'

But the error is not in line 18, it's the empty value for key "hostlist" a few
lines above. So the error should be "hostlist must not be empty, set it to NONE
if you don't want to add hosts to the queue.", or the parser could interpret an
empty hostlist as "NONE".

This issue might apply for all other keys that allow "NONE" as a value, too.

Just seen this misleading error. Apparently caused by an empty pe_list on line 13 reported
as line 26.
