Crashing Settings activity does not return / clean up correctly

[coxtor]

I, I wanted to try out the external plugin possibilities options, sadly the return activity does not function correctly. After exiting the EditData Activity the application crashes, here the logcat:

This seems strange as I can't reproduce the problem.
Could you give a more detailed explanation? Do you encounter this every time you do so?
