seems like a deja-dup issue:

" g_variant_unref () from /lib/i386-linux-gnu/libglib-2.0.so.0
 g_settings_get_string () from /usr/lib/i386-linux-gnu/libgio-2.0.so.0

I can't reproduce this, but I believe this is similar to bug 819109, where we were doing too much work inside the module_load function. So I've committed a fix to delay that work until the next idle loop. Hopefully that fixes this.

[Michael Terry (mterry)]

I see bug 834728 has been filed, which is a very similar issue, just with deja-dup-monitor instead. So I don't think my committed fix will squash this.

How reproducable is this for you? I can't make this happen.
