Bug#778775: session manager and capplet don't receive GSettings notifications with GLib >= 2.43

[Vlad Orlov]

Source: mate-session-manager
Version: 1.8.1-7
Severity: important

With the latest GLib changes [1], if an app reads some data from
GSettings before connecting there, it actually won't receive any
notifications from GSettings afterwards.

The upstream pull request [2] fixes the issue for both session
manager and capplet, making them connect to GSettings before
reading the data.
