Bug Description

I've created 16 bit tiff files with qtpfsgui to use as input files for hugin.

autopano-sift completes the control point generation without any problems, but as soon as you load the resulting pto file into hugin, it crashes with the following error:

$ hugin 16bit.pto
Panorama obj created
hugin: tif_luv.c:292: LogLuvDecode32: Assertion `s == 0' failed.
Could not load pano13Aborted (core dumped)

could reproduce this with 16bit tiff image from qtpfsgui with the following steps.
1. load cr2 image in qtpfsgui
2. save as hdr-tiff
3. open hugin
4. load the image
5. as there is no embedded exif data hugin will ask for focal length...
6. after closing that dialog (regardless if you fill in values or not) hugin crashes.

forgot to mention the hugin version is the recent for fedora 8, qtpfsgui is 1.9.0. 16bit files from bibble work smoothly, no crashes there.

This is not a normal 16 bit tiff, but a LogLuv HDR tiff. Not sure why it crashes, though. Won't fix for 0.7.0

Can it be opened in other applications (cinepaint?)

Yes, it opens fine in cinpepaint, krita and gimp.

in console. I'll take a closer look at it.

I should point out that the LogLuv TIFF is not yet correctly supported, see #735632
