Bottom-frame icons (Network, Battery,Sound etc.) not working on XO-4 (build 28), in ebook-portrait mode

[ajay_garg]

a)
Ensure that build 28 is on XO-4.

b)
Ensure that XO-4 is in ebook-mode.

c)
Rotate the screen, to bring the screen in portrait-model.

d)
When any of these icons is clicked, the palette does not show up; instead the following stacktrace is seen.

Traceback (most recent call last):

Note that things work fine when the screen is in landscape-mode.

The following does update the cached screen width and height variables when the screen dimensions change.

Actually, the second option is to just not cache the dimensions:

I think I prefer that one.

Dup of #3833 - I'm moving the patches there...
