I looked a little bit further. The error (which a bit surprisingly is "End of file during parsing") happens in `widget-apply' which is called from `widget-insert-button-action'. `widget-apply' internally calls Fapply, which is `apply'. The message buffer contains Debug on Error enabled globally End of file during parsing Back to top level. There is no problem just calling a function which gets an error during apply, something like this (defun temp-bad-div(x) (interactive "nNumber: ") (message "%s" (apply '/ 100 (list x)))) This gives the trace-back I expect if called with x=0. `widget-apply' is very short and the crucial part looks like GCPRO2 (newargs[0], newargs[2]); result = Fapply (3, newargs); UNGCPRO; However i have not much idea about what GCPRO2 does so maybe someone who knows that can look a bit further? Why does not the trace-back appear here?
