well, at least it's something. i can confirm that behavior. we'll see if it
actually helps

browser_toolbar_set_common_view
hildon_gtk_im_context_hide(...);

browser_toolbar_hide
hildon_gtk_im_context_hide(...);

on my quest, browser_toolbar_grab_focus_handler seems to be unreachable code
(commented out). browser_controller_hide_all is also unused.

engine_load_progress
if ((!self->toolbar->_is_vkb) || (!GTK_IS_EDITABLE(focus_widget)))

seems fairly suspicious, i wonder if that should be &&.

but, i think the problem is:
engine_window_focused
browser_toolbar_set_common_view(self->toolbar, FALSE);
browser_toolbar_hide(self->toolbar);

so first it tries not hiding it, and then it basically unconditionally hides
it.

Anyway, these are just ramblings of a sleepless engineer. And yes, I know the
sources aren't reachable in svn. I'm sorry, we're working on it.
