In debug mode I start the workbench and click on the DICOM icon. The stack trace shows that it fails during the creation of a ctkFileDialog object, deep in Qt.
see attachment.
I found only this, slightly related: https://bugs.kde.org/show_bug.cgi?id=324177
Does our icon theme have a name?
I did not test on linux.
The reason for this seems to be a missing "folder" icon in our themes. Qt implicitly uses it for the file dialog.

Add folder icons
As an aside, the icon themes currently bundled with MITK are named "tango" and "awesome" respectively.
Icons are located in Plugins/org.mitk.gui.qt.ext/resources/icons/<themename>
Reopening. Doesn't work on Windows in debug mode as an assertion fails regarding an empty theme name.
ASSERT: "!themeName.isEmpty()" in file image\qiconloader.cpp, line 238

Added even more icons
Both themes do not provide the required list icons. For font awesome I used some of the other list icons. The tango project does not, unfortunately contain any list icons, so I created some according to the tango colour scheme. These we might want to replace with some drawn by someone with actual artistic talent and more time.
Does it work now?
I'll check later, thank you.
BTW: Last night I recognized that the Workbench has a strange application icon in the taskbar (Windows). 4 red dots like the 4-side of a dice.
This should not be caused by the icon theme as the application icon is set differently, but I will take a look in the code.
Stefan, your issue might potentially be related to [1].
Is the icon in the top left corner still correct and only the icon in the taskbar shows this strange behaviour?

Sorry, nevermind. It's the Strawberry Perl icon which is used for the command line window since I installed Perl... :-)
