Meld segmentation fault

Running Archlinux -64 with KDE. For gtk apps look I use qtcurve

Just a few days ago meld started segfaulting. When I run it through konsole I get this message

 $ meld
/usr/lib/python2.7/site-packages/gobject/__init__.py:115: Warning: attempting to add an interface (GtkEditable) to class (HistoryFileEntry) after class_init
  type_register(cls, namespace.get('__gtype_name__'))

but it starts. Then, if I hit "directory comparison", and try to browse to a certain directory, it crashes with this message

 /usr/bin/meld:167: GtkWarning: gtk_tree_model_filter_get_value: assertion `GTK_TREE_MODEL_FILTER (model)->priv->stamp == iter->stamp' failed
  gtk.main()
/usr/bin/meld:167: Warning: gtype.c:4239: type id `0' is invalid
  gtk.main()
/usr/bin/meld:167: Warning: can't peek value table for type `<invalid>' which is not currently referenced
  gtk.main()
Segmentation fault (core dumped)

Any ideas, on how to get it working properly again?
I noticed, but that could be irrelevant, that some days ago there was a change with "libsoup-gnome" package. Maybe just a coincidence but after that point, more or less,  I started having the seg faults.
This topic may be  relevant too https://bbs.archlinux.org/viewtopic.php?id=163563

Edit : some more info
Edit II : other topic

Re: Meld segmentation fault

Someone opened a bug report, but meld seems to be working OK for me https://bugs.archlinux.org/task/35439

Re: Meld segmentation fault

Hi, I just ran into the very same problem, even though meld is now 1.8.4

Was this ever resolved?

BTW here's a backtrace:

Re: Meld segmentation fault

meld works for me, I get no messages in the terminal, directory comparison works.

Re: Meld segmentation fault

I also run KDE with GTK2 theme set to oxygen-gtk and it still segfaults. Seems to only segfault with oxygen-gtk and qtcurve.
I tried with gtk-qt4, raleigh and clearlooks and worked fine.

So I see two possible solutions:

1) Either use a GKT2 theme that doesn't cause meld to segfault OR
2) Use your favorite theme that happens to cause a segfault and set only meld to use another theme that works as stated in the wiki.
