The $PYPATH contains "." - dot as current working directory.

According to
http://doc.trolltech.com/4.6/qcoreapplication.html#applicationDirPath
"it assumes that argv[0] contains the absolute file name of the executable"

This assumptions does not hold. On kfreebsd-* the argv[0] usually 
really contains the file name of the executable, but only sometimes 
absolute file name. The argv[0] is just what have been passed by parent
in execve().
