[Nova Launcher] sherpa03:
Problem loading widget

On my Huawei g300 with ICS (official, no root), one single widget does not work and just the message "Problem loading widget" is shown. If I switch to ICS built in launcher, the same widget works. The widget is MyCalendar from Huawei (it is surprisingly nice). This is my only problem with otherwise great Nova Launcher. Is there some settings workaround or could it be fixed?

I checked the phone logs and found this:
