Can't provide a solution but can confirm I have the same
problem. I'm on an Acer Iconia Tab A500 running Android 3.2.1. I
can add the various SuperClock widgets, but Beautiful Home Weather
and Beautiful Smaller Home Weather both result in the force close
error. All fine on my HTC Desire phone. I too uninstalled and
re-installed to no avail.
I have the latest, i.e. no update - 4.0.5
I coped my backed-up APK file of v4.0.4 from my phone to the
tablet. Installed this version and the widget loaded fine. Updated
to v4.0.5 then got force close adding a new Home Weather widget,
although the one I added using v4.0.4 still seemed to work, i.e the
clock was advaning, but the settings cannot be accessed by tapping
the widget, so it must be something new in v 4.0.5?
