Dan,
Today I tried with a simple test-app and the query() method worked
just fine. So I went back to the script that gave me the error and
after some more hours of trials, I suddenly realised that I was
using the wrong signal for my purpose, so the problem is not in your
query() method but in my lack of understanding which signal to use
for which event.....
Sorry for the false alarm and thanks for your reply, but I think
there's no need to look into this issue.

Yikes :)
I'll try to reproduce it here. If not, I might get back to you and ask
for a small sample script that triggers the issue. I have to admit,
since the port from Gtk2, I lost quite a bit of functionality ( custom
cell renderers ) and haven't quite investigated all errors that didn't
cause me immediate issues. Is this actually causing any bugs for you,
or just producing nasty warnings? My guess is that where previously I
had to ( or could ) destroy some signals attached to various things,
maybe the thing this signal is attached to is already destroyed, and
took the signal with it?
Anyway ... I'll look into it. Thanks for using my software :)

Hello,
I started to use Gtk3::Ex::DBI::Datasheet a week or 2 ago and have been
successful with all I needed until I started to use the query() method on an
existing Datasheet object. I tried with and without a where_object but
always get the same result:
GLib-GObject-WARNING **: gsignal.c:2579: instance '0x85952a0' has no handler
with id '1496' at
/home/geert/Documents/proyectos/gladetests/Gtk3/Ex/DBI/Datasheet.pm line
2014.
The line 2014 is where the signal_handler_disconnect is done in the
following chunk of code exctracted from Datasheet.pm:
# Destroy changed_signal attached to old model ...
if ( $self->{changed_signal} ) {
$self->{treeview}->get_model->signal_handler_disconnect(
$self->{changed_signal} );
}
I had a look at the $self object to see if I could find anything wrong with
it, but could not get anything out of that. This is a Data::Dumper printout
of the $self variable right before the above shown chunk of code is
executed:
