I can't reproduce it here with a fresh installation of studio on amd64.
Maybe that could be related to your Gtk theme in some ways? Could you
please try and reproduce with a fresh user?

Hmm, OK. Could we have “bt full” now, so that we have a chance to see
which element is causing you trouble?

Yeah, I noted that.

Eheh, I did not post it before because it's a bit... err.. messy.

Here it is, attaching.

After some more investigation with KiBi on IRC, we decided it's probably a
libgtkmm bug. After installing the proper -dbg package, here's a "bt" and "bt
full" (the latter attached -- please disregard the older one).

OK, got the crash on amd64 as well when upgrading to libgtkmm-2.4-1c2a
from experimental (which is already David's case).

Downgrading severity as a regression (I guess?) in set_tip() for an
experimental package doesn't look as release-critical as synfigstudio
not starting at all; and reassigning (Maintainer/Uploaders Cc'd).

Mraw,
KiBi.

Thanks for the report.

The "tootips" API has been deprecated in GTK+ since 2007-07-09, and in
gtkmm as well with the following changelog:

and with the following patch (edited to get rid of comment part):

So it looks weird the following if-statement still get passed in.

As noted in changelog, this problem doesn't look like to get fixed any
more.  Synfigstudio upstream may consider migrate to the new API of
Gtk::Tooltip (note without 's').

I'll contact gtkmm upstream for further information.

You don't seem to have identified the actual problem. If that above
synfig code is correct then this is nothing to do with the gtkmm or GTK+
change.

OK now I get it:  I mistakenly downloaded the synfigstudio version
0.61.09-1 from Debian experimental.  In version 0.61.08-1 the code
reads:

330        ret->set_label(tooltip);
331        toolbar_->get_tooltips_object()->set_tip(*ret,tooltip);

Which explain the crash with gtkmm 2.14+.  Reassigning to synfigstudio
and mark as fixed in version 0.61.09-1.
