Bug#831453: meld crashed when invoked from command line after recent upgrade (suspect GTK)

[Chris Tillman]

Package: meld
Version: 3.16.1-1
Severity: normal

Dear Maintainer,

Hi,

I invoked meld with two small documents.

        $ meld 6100.1.chk 6100.2.chk

The result was

No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified
Unable to init server: Could not connect: Connection refused

(meld:14422): Gtk-CRITICAL **: gtk_icon_theme_get_for_screen: assertion
'GDK_IS_SCREEN (screen)' failed
Traceback (most recent call last):
  File "/usr/bin/meld", line 260, in <module>
    setup_resources()
  File "/usr/bin/meld", line 193, in setup_resources
    Gtk.IconTheme.get_default().append_search_path(icon_dir)
AttributeError: 'NoneType' object has no attribute 'append_search_path'

I noticed bug 830952, so checked my GTK version; it was 3.20.6-2. Perhaps "too
new"?

When I opened meld through the menu instead, I was able to use it to view the
diff.

Let me just say that I think meld provides the most attractive diff result
display I have ever seen, it's a joy to use just because of that.
