Meld crashes when selecting the first directory to compare

[vmagnin]

I open Meld 1.8.1-1 (Kubuntu 13.10), I click on "Directory comparison", then I try to select the first directory and Meld crashes. From command line, I obtain the following messages:

$ meld

/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: /build/buildd/glib2.0-2.38.1/./gobject/gtype.c:4215: 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()
Erreur de segmentation (core dumped)

Meld crashes also when I click on "Version control view".
But "File comparison" is working.

[vmagnin (vincent-magnin)]

The directory comparison works fine launching meld with command line:
meld directory1 directory2

The bug is thus probably related to the directory selection window.

Status changed to 'Confirmed' because the bug affects multiple users.

Meld 1.8.4 + Kubuntu 14.04

An workaround that worked for me is to change the gtk theme. In Kubuntu go to "System and Settings" -> "Application Appearance" -> "GTK" -> "Select a GTK2 Theme", and change the theme.

[vmagnin (vincent-magnin)]

I confirm wcg's workaround. With the oxygen-gtk theme, meld crashes when selecting the first directory to compare. With the not so pretty Raleigh gtk2 theme, it works fine.

Meld 1.8.4 + Kubuntu 14.04

[Daniel Semblano (dsemblano)]

I can confirm this too, Meld 1.8.6 + Kubuntu 14.04. I did as wcg said and worked.

[uNickus (astatest)]

I have find additional workaround:
work with GTK3 by running of directory comparision from console, like
meld <dir1> <dir2>

GTK2 themes are so terrible :(

And i check this problem on devel version 3.11.3 with following requirements:

Python 2.7 (Python 3 not yet supported)
GTK+ 3.6
GLib 2.34
PyGObject 3.8
GtkSourceView 3.6

And got:
(meld:25034): Gtk-CRITICAL **: gtk_tree_model_filter_get_value: assertion 'GTK_TREE_MODEL_FILTER (model)->priv->stamp == iter->stamp' failed
/usr/bin/meld:227: Warning: /build/buildd/glib2.0-2.40.0/./gobject/gtype.c:4210: type id '0' is invalid

/usr/bin/meld:227: Warning: can't peek value table for type '<invalid>' which is not currently referenced
  status = meld.meldapp.app.run(sys.argv)
Segmentation fault (core dumped)

But devel version is unstable, and file compare is not working too, with another error:

[JungleEditor (subscriptions-ruadesign)]

I have the same issue (Kubuntu/meld 3.12.1-2) - crashes when choosing directory, but $meld <dir1> <dir2> works fine

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[vmagnin (vincent-magnin)]

The bug is solved in Meld 3.12.3-1 (Kubuntu 15.04 64 bits, GTK+ 3.14.12).

[Mariano (marianocali)]

I am using Kubuntu 14.04 LTS and Meld it crashes when selecting the first directory to compare.
I try with Meld 1.8 and I download Meld 3.14 and I have the same problem with both.
I try to change oxygen-gtk theme to all the others but crashes also
In a console comparation it works Ok
