If I have a valid program (not an empty text file) and I try to insert a character at the beginning of the file, then most of the times it throws the following exception and the editor will hang:

This happens when inserting, for example, a new line or a space (i.e. the resulting program is still valid) or when inserting a random symbol (i.e. the resulting program is invalid).
