Bug#770899: meld: Meld crashes when modifiying a file externally

[Manuel Luque]

Package: meld
Version: 3.12.1-1
Severity: normal

Dear Maintainer,

I was comparing two files in Meld, when I modified one of them externally (out
of Meld) and then Meld crashed.

The messages appearing in console are:

---------------------------------------------------
(meld:7014): Gtk-CRITICAL **: _gtk_rbtree_reorder: assertion 'tree->root->count
== length' failed

(meld:7014): Gtk-CRITICAL **: _gtk_rbtree_reorder: assertion 'tree->root->count
== length' failed
**
Gtk:ERROR:/build/gtk+3.0-5i5HPl/gtk+3.0-3.14.4/./gtk/gtkrbtree.c:465:_gtk_rbtree_insert_after:
assertion failed: (_gtk_rbtree_is_nil (tree->root))
Aborted
---------------------------------------------------


I would expect Meld not to crash in this scenario.
