DS crashes after undocking states view

Attached DS configuration file and workspace files with which I get the crash. What happened was:

• I installed latest snapshot of 3.8 from the online installer (--staging-commercial)
• I opened workspace file "RTA"
• I undocked new States editor
• -> Suddenly I had two states editors -> One undocked and one docked as in picture3.
• When I docked the states editor again all views seems to be something other than what the title said -> e.g. opening translations view showed states view etc
• I closed DS and reopened
• I opened a project and tried to switch to workspace "RTA"
• -> DS crashes
