Miika Turkia bdedf46e4c Get rid of compiler warning on format strings 
This gets rid of compiler warnings "format not a string literal and no
format arguments [-Wformat-security]". E.g. when building distribution
packages these warnings are often treated as errors preventing the
build (with good reason).
