I think I can fix this. Quick question though, was the file you were diffing in a git repository?

[kadecole]

Yes the file was part of a git repository.

[mupchrch]

Anything special about the file or repository? For instance, was the file not part of the repo / not committed yet? Did you rename the file? It looks like the latest copy of the file from the branch couldn't be opened, so it tried to set your second pane text to null.

Sorry for all the questions, just trying to figure out if there is a way to fix it so that it will show you your git changes instead of failing and opening with a blank pane.
