Stop assuming that priv->label_widget will be a GtkLabel. (2.78 KB, patch)

Description Praneeth Venkata 2010-07-05 13:38:06 UTC 
I have build meld(http://meld.sourceforge.net/) using pygtk-2.16.0 and gtk+-2.20.1 as one of its dependencies. I am getting the below warnings when I do a directory diffing. These warnings occur only when I use pygtk-2.16.0 and not evident when I use older versions of pygtk. 

Can someone please quickly help me debug this issue? 

Command I run 

/usr/pkgs/meld-1.3.1/bin/meld /usr/local/etc /usr/local/bin

Warnings 

/usr/pkgs/meld-1.3.1/lib/meld/dirdiff.py:262: GtkWarning: gtk_label_set_ellipsize: assertion `GTK_IS_LABEL (label)' failed
  self.filter_menu_button.set_label_widget(label)

This is reproducible always
Comment 1 Praneeth Venkata 2010-07-08 12:54:24 UTC 
This happen to occur when I build pygtk with latest GTK-2.20.1. These warnings does not seem to occur with older gtk.
Comment 2 Tomeu Vizoso 2010-07-12 15:04:59 UTC 
Gtk+ started to (incorrectly) assume that all widgets set with gtk_tool_button_set_label_widget are GtkLabel(s) at this commit: http://git.gnome.org/browse/gtk+/commit/?id=dad6e734 .

Stop assuming that priv->label_widget will be a GtkLabel.

Please backport to 2.22
Comment 4 Praneeth Venkata 2010-07-23 11:02:06 UTC 
Thanks for your help here, I shall rebuild gtk with your patch and let you know. I was wrong in comment1 and these seems to occur with both gtk+-2.18.3 and gtk+-2.20.1.
Comment 5 Praneeth Venkata 2010-07-23 12:25:29 UTC 
Awesome. This patch has fixed my issue. I rebuilt gtk+-2.18.3 with this patch.

Thanks Vizoso for your help
