Reading Package Lists... Error!
E: Dynamic MMap ran out of room
E: Error occured while processing libgtk2.0-0 (NewVersion1)
E: Problem with MergeList /var/lib/dpkg/status
E: The package lists or status file could not be parsed or opened.

I scrolled through the /var/lib/dpkg/status file, and nothing seemed
amiss.  It's 577kb, though.  The libgtk2.0-0 section looked fine, also.

Any idea what's up?

TIA
