#27 image cache problem causes thumbnail regeneration

[Anonymous]

in the imageSize function:

sizestr = fcachesizes.lookup(path)

which sometimes returns 0x0, which then gets returned
to generateThumbnail, causing it to fail the
checkThumbSize test.

To fix it, I changed
if sizestr != None:
to
if sizestr != None and sizestr != "0x0":
