Yes. Use Control.Exception.catch The catch in the Prelude is only for catching IO errors. It cannot catch errors thrown from pure code. Note that you can only catch exceptions in IO. > I use quite a few functions that produce errors (also from gtk2hs). > These functions have been programmed using "error."

I thought gtk2hs mostly throws exceptions in IO (which can be caught in IO) except for some rare cases which would always be programming errors. If you can report them we can fix them.
