Description of problem:

The latest libtiff (3.9.4-3) seems to have problems decoding some G4 images
which the previous version (3.9.4-1) was happy with.

Version-Release number of selected component (if applicable):

3.9.4-3

How reproducible:

Every time on problematic images.

Steps to Reproduce:

1. Run "tiffinfo -D" on the image
2. Observe the errors
