I assume you use the version 1.8.x?  If so, there was a
feature/bug there that was reverted in more recent versions back
in 2012, because of its ambiguous results. AFAIR, if a net had at
least two connections to symbol pins (probably, on different
pages, I cannot remember), its dangling ends showed as you
describe it here. The commit 013e175 and its predecessors in the
geda-gaf or lepton-eda repos can shed some light on this, though
the main discussion happened on launchpad (or maybe here on the
list).
