Bug#637921: crash in viking while saving an unrelated file in Emacs

[Vincent Lefevre]

In viking I was viewing track properties, then it crashed. Actually
the crash occurred while I was *not* using viking. It occurred at
the same time I was saving a modified file in Emacs (this file was
not one open in viking, so that's quite surprising).

In the terminal where I started viking:

** (viking:18631): WARNING **: Unknown GObject type 'VikWmscMapSource'

(viking:18631): GLib-GObject-WARNING **: g_object_set_valist: construct property "lat-attr" for object 'VikGotoXmlTool' can't be set after construction

(viking:18631): GLib-GObject-WARNING **: g_object_set_valist: construct property "lon-attr" for object 'VikGotoXmlTool' can't be set after construction

Gtk:ERROR:/tmp/buildd/gtk+2.0-2.24.22/gtk/gtkfilesystemmodel.c:746:gtk_file_system_model_sort: assertion failed: (r == n_visible_rows)
zsh: abort (core dumped)  viking

The backtrace:

Core was generated by `viking'.
