Comment (by elelay):

 This is a crash in g_settings_set_property, most likely due to it not
 finding the GTK3 glib schemas (/opt/local/share/glib-2.0/schemas/).
 I fixed a similar problem in gPodder:
 https://github.com/gpodder/gpodder/issues/413

 Strange that dtruss doesn't show an error related to this.

 1. run `G_DEBUG=all meld`
 2. check that you have `/opt/local/share/glib-2.0/gschemas.compiled` and
 `/opt/local/share/glib-2.0/org.gtk.Settings.FileChooser.gschema.xml`
 3. if you have a XDG_DATA_DIRS environment variable, does it contain
 /opt/local/share. If not, it might be worth a try to run
 `XDG_DATA_DIRS=/opt/local/share meld`
 4. try reinstalling glib2
