Crash when selecting changed file - The number of elements in this collection must be less than or equal to '65535'.

Clicking on a changed file (in our case a css file) causes an immediate crash. Now when re-opening the application, since that file is the currently selected file, it immediately crashes. Our developers are all having to revert back to the previous version.

I've attached the log file.

Here's a quick summary of the issue in the log:

ERROR [2016-02-17 10:12:28,205] [1] [SourceTree.AppRoot] [HandleCrash] - Fatal error
System.ArgumentException: The number of elements in this collection must be less than or equal to '65535'.
