after MitkDiffusion --BlueBerry.Clean and selecting a perspective from the welcome page (e.g. dicom import or preprocessing), MitkDiffusion crashes on closing with status 134 and core dump.

This behaviour (crash-on-close with status 134 and core dump) stays the same
on subsequent starts, even when doing nothing but closing the workbench.

Sometimes the MitkDiffusion programm crashes on starting, with status 134 and core dump.

--BlueBerry.Clean remedies this, but only once and if no perspective is selected.
