XML Import in console broken

• in the cms console, choose XML Import
• click Browse and choose a file (see attachement)
• leave all settings at default values
• click "import"
• node is imported, but GUI does not work anymore, can't click on any button (e.g. write changes to repository)
• you have to logout and login again for the GUI to work again
• so you can never save an imported node (therefor I marked this issue as a blocker)

I have attached an example XML to import (test.xml), but I have seen it happen with all the files I tried, even those that I just exported from the same application instance.
