Latest Master branch. Build with MITK_BUILD_CONFIGURATION=MitkDiffusion and CMAKE_BUILD_TYPE=Release.
Trying to quit MITK results in error message. (see screenshot attached)
(Maybe helpful: while still running (before quitting) it says on the terminal: "[BlueBerry] LOG: Warning: Detected recursive attempt by part org.mitk.views.viewnavigatorview to create itself (this is probably, but not necessarily, a bug)")
OSX version: 10.10.5
This does not happen with the MitkWorkbench (when building MITK_BUILD_CONFIGURATION=MitkWorkbench).
