Hi, a little problem I meet here: I can't open the widget manager application...

The patch is applied (No date/time on lockscreen), but the widget manager can not open. (Circling for a while and exit)

So I tried the following:
1. unapply all other patches -> not work
2. uninstall all other patches -> not work
3. reboot -> not work
4. unapply, re-apply -> not work

Sailfish: 2.0.0.10

Is there any place I can find a logging record? Did I miss anything?
