Failed to allocate memory for to read TIFF directory (0 elements of 12 bytes each)

[Derek Magee]

Disclaimer: I'm nothing to do with openslide development

I had a quick look at this image and it doesn't seem formatted like a regular svs file . It only contains 2 images in the TIFF (presumably full resolution and thumbnail). It <sort of> reads ok in imagescope but is very blurred until you get to native resolution (which fits with absence of levels 4 and 16). If it was me I'd get this file rescanned.
