Error with Duplicate File Names

[kesslerm]

I've had an issue with the 2027 builds and the Alpha is crashing worse with this path.

Open up properties of a file.
Rename the file to an existing file.
Click OK.
A dialog box pops up asking if you want to replace the existing file.
Click No.
Most times an access violation shows up or MM crashes hard.

I was unable to reproduce, it all worked as expected. Please capture the crash in a debug log (step 4b) and attach the log to a Support Ticket: viewtopic.php?t=86643

This will help a developer analyze why this happens on your setup.
