Regression: Exception when opening a conflict

[mdk]

I got a conflict. When I try to "Resolve" the conflict, I get the below Exception.

I test the same with last stable version r7995 without problems.

To Reproduce, I striped down a saved file (see attachment). Load the file and choose *Update Data" from File menu. You will get a conflict. Try to resolve the conflict.
