WirelessSecurityWPAEAP is a GtkWidget owned by the CEPage8021xSecurity
widget, which is supposed to "unparent" it on "dispose" (since parents
hold a reference to child widgets). Instead we were calling
g_clear_object on it.
Fixes#1671
Weak references are added when logical monitors are created, however we
don't remove them when destroying the display.
This means that if a monitor survives to the display finalization
(because may be referenced elsewhere) it will make g-c-c to crash
during its finalization, as that will trigger the weak reference
callback that will try to access to the already-finalized display.
getlogin() can fail for several reasons as detailed in the man page, and
the current behaviour is a segmentation fault when it fails with NULL,
such as due to an unset loginuid.
* Check return value for error and act accordingly.
* Change to getpwuid(getuid())->pw_name, which is less likely to error.
Instead of using a plain "flat" button positioned at the window corner,
let's use GtkWindowControls to wrap the close button and get the
default window control styling and alignment.
Fixes#1737
Make sure to keep a reference to the GoaObject of the account around so
that the GBinding that synchronises each switch widget and the account
properties don't get finalized on startup.
