#199 If second arg is non existant directory causes execption

[Anonymous]

If the second directory argument to xxdiff does not exist an exeception is thrown. All other combinations of path arguments appear to work correctly.

$ xxdiff valid-directory/ not-valid-directory/
Throwing exception:
xxdiff (app.cpp:665):

Internal error.
