Problem: You have found a bug in the CHDK.
Solution: First check to see if the bug persists in the newest version of the
CHDK. If yes, and if you have access to another camera, find out if the bug
is specific to a certain camera model or not. Then file the bug in the Mantis
bug tracking system (http://chdk.kernreaktor.org/mantis). Before you do,
please check to see whether a similar bug is already filed there.
