Crash when choosing a directory

[Reto Meier <reto meier bfh ch>]

Hello 
I updated my Kubuntu today. Now Meld crashes with the following messages:

/usr/bin/meld:172: GtkWarning: gtk_tree_model_filter_get_value: assertion 
'GTK_TREE_MODEL_FILTER (model)->priv->stamp == iter->stamp' failed
  gtk.main()
/usr/bin/meld:172: Warning: 
/build/buildd/glib2.0-2.40.0/./gobject/gtype.c:4210: type id '0' is invalid
  gtk.main()
/usr/bin/meld:172: Warning: can't peek value table for type '<invalid>' which 
is not currently referenced
  gtk.main()
Segmentation fault (core dumped)


This occurs each time I try to choose a directory in the "Directory 
comparison". The drop down works. But as soon as I choos something, it 
crashes. Choosing files works. 

The installed version is 1.8.4.

Can you help me?

Thank you
Kind regards
