Description Murray Cumming 2014-12-22 11:28:01 UTC

Glom now shows a Gtk-CRITICAL warning like so when quitting:

  (glom:11677): Gtk-CRITICAL **: gtk_widget_get_parent: assertion 'GTK_IS_WIDGET (widget)' failed

 I think it's triggered by newer GTK+ versions. Here is the backtrace at the warning:

Comment 1 Murray Cumming 2014-12-22 11:36:56 UTC

Valgrind doesn't seem to show any relevant warnings other than the usual warnings about Python.

Comment 2 Murray Cumming 2015-01-15 07:49:57 UTC

This is fixed (well, worked around) by this commit:
