--- Comment #14 from Christian <gentoo at moin.fi> ---
Dear Gilles! Thanks for the help.

The first error that valgrind reports is the following. I know that it spews
out lots of text when it finally crashes (that's why my earlier Valgrind log
only contained the end of the output). Now I'm sending the output to a file
(--log-file=...) so I can report it here. Does this initial error already help
in pointing down the bug? (It happens when I correct the name on a face with a
"guessed" name. The name is saved in the file but after a while Digikam
crashes.) Using Digikam-4.2.0.
