Sorry, I assumed that since it's get_widget() that causes the segfault, the
try/catch would need to be around it. I'm not aware of any exceptions it may
throw. My mistake.

I guess this leaves us with fixing the documentation about the exact exceptions
being thrown by, say, add_from_file() (I can think of at least three:
Glib::FileError, Glib::MarkupError, Glib::BuildError). We will probably have to
wait for gtk bug http://bugzilla.gnome.org/show_bug.cgi?id=560147 to be
resolved.

------- Comment #11 from Daniel Elstner  2009-07-21 22:12 UTC -------
Is this a jhbuild session?  Are you using the system glibmm or did you build
that from git as well?

If you built glibmm yourself, it could be that the M4 file with the macro has
been installed to a location where aclocal doesn't look for it by default. In
that case, adding the necessary -I option to the ACLOCAL_FLAGS environment
variable should help. For a quick test, just installing the distribution's
glibmm development package should make it work, too.

It seems that we wrap the add_data() with a std::string argument and a raw
pointer argument, but the raw pointer one doesn't provide a way to specify a
free DestroyNotify function nor does it document that we (apparently) free it
ourselves.  The raw pointer overload should probably be deprecated and wrapped
properly.
