Description Ruslan Kabatsayev 2011-01-20 20:42:52 UTC

I get these errors when the window of the program attached is closed:


(test:9906): GLib-GObject-CRITICAL **: g_object_ref: assertion `object->ref_count > 0' failed

(test:9906): GLib-GObject-CRITICAL **: g_object_ref: assertion `object->ref_count > 0' failed

This is only when GtkComboBox::appears-as-list=1 is set in gtkrc.

Comment 2 Daniel Boles 2017-08-24 00:46:03 UTC

If you can still reproduce this (I assume yes), it would be great if you had posted a backtrace with debug symbols to each critical.

Comment 3 Daniel Boles 2017-08-24 01:32:55 UTC

I can't reproduce this on GTK+ 3. In contrast, I can on GTK+ 2, but I don't have a debug version of that immediately available, so the backtrace I got is useless.

Comment 4 Daniel Boles 2017-08-24 07:30:37 UTC

This system has a slightly less useless GTK+ 2 build, but still not much help.
