Description Jonathan Kang 2017-04-06 09:54:45 UTC 
Already connected to a wifi network

Steps to reproduce:
1. click the gear button on the wifi that has been connected
2. close the details dialog popup
3. click "connect to hidden network" button

The following steps can also reproduce this bug:
1. click "connect to hidden network" button
2. close the dialog popped up
3. click the gear button on the wifi that has been connected

Then the following errors show up in the command line:
(gnome-control-center:9016): GLib-GObject-CRITICAL **: g_boxed_type_register_static: assertion 'g_type_from_name (name) == 0' failed

(gnome-control-center:9016): Gtk-CRITICAL **: gtk_list_store_set_valist: assertion 'GTK_IS_LIST_STORE (list_store)' failed

And the program hangs.


By using gdb, I get the following backtrace:

This issue seems to be introduced by commit 0470c040b1e6f5f2b1eba852e15365579ce1dba5.

Works fine here. You'll want to check your downstream patches.

This means that the type was already registered:
"
(gnome-control-center:9016): GLib-GObject-CRITICAL **: g_boxed_type_register_static: assertion 'g_type_from_name (name) == 0' failed
"

Check the backtrace of this warning, and find out what type is doubly registered.

This issue happens in terms of the code base in master branch. So there are
no downstream patches.

EAPMethod is registered twice. See the backtrace below:

I'm using network-manager-applet and libnma 1.8.0, can you check whether this happens with this version, or are you using network-manager-applet from git master as well?

I'm on the master branch of network-manager-applet, which is version 1.7.1.

Reverting commit 0470c040b1e6f5f2b1eba852e15365579ce1dba5 fixes the problem.

Is it because EAPMethod has already been registered in network-manager-applet?
I found that in commit 0470c040b1e6f5f2b1eba852e15365579ce1dba5, CcEAPMethod
was renamed to EAPMethod, which is the same name as the type in
network-manager-applet.

This issue still exist with the latest code in master branch.
