gnome-control-center on precise crashes when the network panel is closed

Bug #1234392 reported by bug bridge on 2013-10-02
This bug affects 2 people
Affects Status Importance Assigned to Milestone
gnome-control-center (Ubuntu)

Bug Description

[ Description ]

The patch to fix flight mode SRUed in 3.4.2-0ubuntu0.12 caused a crash in the network panel.

[ Test case ]

1. Open gnome-control-center
2. Click on "Network"
3. Close gnome-control-center

In the bad case, you'll get a crash at 3. After the update, you should not.

[ Fix ]

Pass a pointer of the correct type to g_hash_table_destroy.

[ Regression potential ]

Can't think of anything specific that might break because of this. Try the panel out and see if it generally works as before.

[ Original description ]
