Dear maintainer ! I can confirm that installing the debian Stretch version (libtiff5_4.0.6-2_amd64.deb) fixes the problem on Jessie. Regards, Karl Kashofer On Mon, 8 Aug 2016 11:46:25 +0200 "n...@tcrass.de" wrote: > Dear maintainer, > > > However, the problem seems to have been fixed in libtif

Dear maintainer, However, the problem seems to have been fixed in libtiff 4.0.5. Now there's also 4.0.6, which I haven't tried: http://download.osgeo.org/libtiff/ would it be possible to pull testing's 4.0.6 version to stable? It seems to work fine in a Jessie environment, as I figured out wh
