Gitextensions: [NBug] 0 <= offset < 9631. Parameter name: offset.

Current behaviour

I simply navigate and search between files in a previous commit (File tree). A new search "Find next" give me this error.

Expected behaviour

Search the text (highlight text and jump to the location)

Steps to reproduce

I don't know how to reproduce now. Previous searches work fine.

I also ran into this bug today. It specifically happens on Find (selection only) operations.
Steps to reproduce:

1. Select at least two lines from the file diff view.
2. Open the find window (should now say selection only).
3. Search for some text that is not in the selection that was made in step 1. The application will then crash.

Note: The application only crashes when doing a find next/previous. Find all and highlight does not cause a crash.
