I can't reproduce the issue (Windows, Fedora and Ubuntu tested). When loading the files in Hugin no warning pop up. The cli tools issue the warning on cout/cerr, but no popup. So without more information why the popup comes only on your side I can't debug it further.
PS: The cause of the warning should be fixed in darktable (libtiff and exiftool bring the same warning about the wrong metadata). -- You received this bug notification because you are a member of Hugin Developers, which is subscribed to Hugin. https://bugs.launchpad.net/bugs/1635992 Title: Null count for "Tag 50341" (type 7, writecount -3, passcount 1) (in module "_TIFFVsetField") Status in Hugin: New Bug description: Hugin 2016.2.0.be8da0221960 from PPA on Xubuntu 16.04 Trying to stitch a couple of TIFFs created with Darktable The following error keeps popping up: Null count for "Tag 50341" (type 7, writecount -3, passcount 1) (in module "_TIFFVsetField") Hugin does its work, but clicking away the multiple error message (for each image, and it seems to come up every time the image is displayed) is a painful papercut To manage notifications about this bug go to: https://bugs.launchpad.net/hugin/+bug/1635992/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~hugin-devs Post to : hugin-devs@lists.launchpad.net Unsubscribe : https://launchpad.net/~hugin-devs More help : https://help.launchpad.net/ListHelp
