I was able to reproduce with a fairly recently compiled geda from git-
head. The errors seems to be triggered by the "refdes=POWER" attribute 
of the sub sheet symbol. If I change this to "refdes=POWE", the above 
errors disappear. "refdes=POWeR" was fine too. Seems like the string 
"POWER" gets some kind of special treatment. 

Settings of the various mangle options in gnetlistrc did not influence 
the DRC errors.

This was a wise decision. The netlist produced by gsch2pcb did contain 
the dangling nets DRC was complaining about. A layout based on this 
netlist would have been broken.
