Currently the first start of the MITK Workbench will crash on Windows. It should not.
It seems like this bug is related to the plugin list created by the ctkPlugin framework. At a certain point, which is not clearly reproducable yet, the plugin list is corrupted and the execution crashes, but only after /BlueBerry.clean.
Switching off all plugins helps to eliminate the crash.
Next step is to systematically add the plugins until the crash occurs again.
I tested whether changing the ITK_NO_IO_FACTORY_REGISTER_MANAGER behaviour affects the bug. Unfortunately neither 1 nor 0, nor forcing one execution of the MITK_ITK_CONFIG.cmake with 0 and subsequent ones with 1 changed the crash in any way.
