Package: libtiff4 Version: 3.9.6-11+deb7u2 Severity: normal On a wheezy system with libtiff4-3.9.6-11 the following works without a problem:
mogrify -compress JPEG sample.tif and adds JPEG compression to the formerly uncompressed sample.tif. After upgrading to 3.9.6-11+deb7u1 or 3.9.6-11+deb7u2 this results in an error: sample.tif: Invalid tag "Predictor" (not supported by codec). `_TIFFVGetField' @ error/tiff.c/TIFFErrors/508. This also results in a corrupted image file which now includes "Predictor: 2" according to tiffinfo, which I believe should not be there in this case. The resulting file is attached as broken.tif
