[sigc] exception_catch and parameters

[Florian Philipp <lists binarywings net>]

Hi list!

Sorry if this is a dumb question but I cannot really figure this out:
Can I use the exception_catch adaptor with slots that pass parameters?
If the answer is yes, what is wrong with this code:

class SlotExceptionHandler {
  void operator()();
}
SlotExceptionHandler* exception_handler;
slot<bool, Glib::IOCondition> real_slot;

slot<void> except_functor = mem_fun(*exception_handler,
  &SlotExceptionHandler::operator());
slot<void, IOCondition> param_except = hide(except_functor);
slot<bool, IOCondition> return_except = bind_return(param_except, true);
slot<bool, IOCondition> combined_slot = exception_catch(real_slot,
  return_except);

gcc aborts on the last line:
/usr/include/sigc++-2.0/sigc++/adaptors/exception_catch.h:82: error: no
match for call to ‘(sigc::slot<bool, Glib::IOCondition, sigc::nil,
sigc::nil, sigc::nil, sigc::nil, sigc::nil, sigc::nil>) ()’
/usr/include/sigc++-2.0/sigc++/functors/slot.h:512: note: candidates
are: T_return sigc::slot1<T_return, T_arg1>::operator()(typename
sigc::type_trait<T_derived>::take) const [with T_return = bool, T_arg1 =
Glib::IOCondition]

If it's relevant: This is a SuSE Enterprise distribution, GTK+ is around
2.18, Gnome 2.28. I cannot check the sigc version right now.

Thanks in advance!
