I am not exactly sure what is causing this exception but the stack trace contains only System.* namespaces so the problem will most likely be in mono implementation of winforms. My testing shows that this exception is related only to hexbox package (libhexbox package is unaffected) and the application functionality seems to be unaffected also - it is just an exception printed into the console when the application is closed. I think it can be ignored.
BTW I have examined "debian/control" file of the package and it seems the descriptions for "hexbox" and "libhexbox" packages are swapped.
