Bug Description

In USS I am trying to add a schema which has a a{ss} key. Upon opening USS, it crashes with the following output:

ERROR:qconftypes.cpp:295:QVariant qconf_types_to_qvariant(GVariant*): code should not be reached
Aborted (core dumped)

QML code: http://pastebin.ubuntu.com/7893911/
Schema: http://paste.ubuntu.com/7902850/

Goes for a{ss} as well, if it makes any difference.

I'm hesitant to add support for writing arbitrary variants, because there's no way to specify which type exactly you want to write from qml. gsettings-qt coerces whatever you write into the type expected by the schema, but it can't do that for a{sv}.

What exactly do you need this for? Laney hinted that you might be okay with just having a a{ss}?

Sorry, sv was actually a mistake on my part. It was just a part of debugging: I thought a{ss} killed the app and tried a{sv} instead (since I observed that this was used in other schemas. Somehow it made it in to this bug.

a{ss} is all I really need.
