Log message:
Apparently every error case was reported except for the most common
-- "your system does not handle shared pixmaps" .  It was already
caught and handled though.  :)

Anyhoo.  This commit adds in slightly saner error trapping, and
significantly improved error reporting.  No functional changes at all.

Enjoy, folks...
