************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

How to repeat:
hard to say, but it happened when I removed a relation that had a column referenced to it, the column got removed..and the crash occured.

Hello Ayvind,

would it be possible to submit your model to this report (can be done via files tab; also possible to submit it "private") and/or describe the steps you took to encounter the crash?
