There seems to be a problem with the path separators. An example path on my Windows machine is:
C:\Users\franza\AppData\Local\Temp\/G0B3X3
The "\/" in there seems to lead to some problems, e.g., when trying to separate a filename from this directory.
Seems as this bug could be avoided by calling the method with parameters. For example:
mitk::IOUtil::CreateTemporaryDirectory("NavigationToolStorageSerializerTmp_XXXXXX",mitk::IOUtil::GetProgramPath())
returns a valid path!
When, e.g. one "X" is forgotten like here:
mitk::IOUtil::CreateTemporaryDirectory("NavigationToolStorageSerializerTmp_XXXXX",mitk::IOUtil::GetProgramPath())
the path is valid again.
Maybe this helps to fix the bug!
there is a typo in the last commen, in the second case:
"... the path is INvalid again."
There was another problem on the dashboard possibly caused by this bug:

The error message:
