libdbusmenu-glib crashes nm-applet due to new GVariantBuilder code

[Michael Terry]

With latest libdbusmenu-glib in natty (0.3.91-0ubuntu1), I get occasional crashes in nm-applet. In the console, it spits out:

(nm-applet:21976): GLib-CRITICAL **: g_variant_builder_end: assertion `!GVSB(builder)->uniform_item_types || GVSB(builder)->prev_item_type != NULL || g_variant_type_is_definite (GVSB(builder)->type)' failed

And its stack trace is (CoreDump attached):

This frequently causes nm-applet to crash, which disabled wireless until nm-applet is restarted.

This also affects i386, not just amd-64.

Confirming, since there's at least one filed duplicate..

This bug was fixed in the package libdbusmenu - 0.3.92-0ubuntu3

---------------
libdbusmenu (0.3.92-0ubuntu3) natty; urgency=low

  * libdbusmenu-glib/server.c
    * Better error handling when parsing g_variants (LP: #703039)
