Toolbar looks fixed, but actions don't work before opening preferences once

Setup (please complete the following information):

• Distribution: Debian
• Distribution release: stable
• Geeqie version [geeqie --version]: latest git

Describe the bug The fix for the bug #1450 seems to have fixed the looks of the buttons and part of the behavior, many thanks for that - BUT, now that it works I have discovered that it doesn't work correctly until I go to preferences (I don'ẗ even need to go to the toolbar preferences tab, just open the preferences window) and press OK to apply them before it works properly. Before I do this, pressing a plugin toolbar button just gives

(geeqie:74135): Gtk-CRITICAL **: 18:32:37.349: gtk_action_activate: assertion 'GTK_IS_ACTION (action)' failed

in a terminal, but no action. After going to the preferences, pressing OK to apply them, the toolbar plugin button works just fine. Doing some research it looks like the function config_window_apply() in preferences.cc calls toolbar_apply(TOOLBAR_MAIN), which isn't called before this, this might be related. This might be a config thing specific to my setup, but I kind of doubt it.

To reproduce See above ^.

Expected behavior Toolbar plugin buttons working without having to go to preferences first to make it work.

And to make things clearer, the problem seems to be only for plugin buttons.

@gusnan Thanks. I see the problem, but did not yet find a solution.
