Fix #23188: libpng error: Image width or height is zero in IHDR.

Browse Source 
The file thumbnail generator would write 0x0 size png's to the .thumbnails/fail
folder. However libpng throws an error when doing this. Instead we now write 1x1
png's, which nautilus seems to be doing as well. The content shouldn't matter
anyway since we won't use it.
