The change is in the default branch of our mercurial repository.
You need to compile yourself. For Ubuntu there are nightly build available, but
I know no binaries for other systems in the moment.

How can I test it out?
Do I download a beta version of nona?

Title:
EXR files quietly clipped
Hugin is using absolute ev values in the exr files. Therefore clipping can
occur, when the value range of the exr file is overrun (as already found out).
A possible solution is the use relative ev values in the exr files (Implemented
in changeset 7b8ada736647). This changes the behaviour when out
Shortly – it may work.
Nona is a part of hugin. libpano is used for position optimization.
Tools used to create images are certainly different in PTGui.

If I buy a commercial program such as PTGui, will it offer a solution to this
issue with nona?
I had heard that both Hugin and PTGui use the same panotools programs under the
hood e.g. nona.

This page is such a relief! I am not the only one suffering from serious HDR
issues.
Have got much better at shooting HDR 360 panos, but have been getting worse (if
any) results from Hugin!
The most successful approach I have found on recent versions of Hugin is
to process my images in 32bit Tif
I should say now that on HDR panoramas stitched from many (e.g. 35+)
exposures, now I am almost always getting this bug, which renders the
entire HDR black. If I stick the EV=0 and EV=+2 exposures then I get a
usable HDR, but when include the EV=-2 exposures I get a black output.

Also agree that the TIFF workaround does not work in the latest version
of hugin on OpenSuSE 11.4

Feel a bit miffed that this bug is assigned "low priority status". I
have had several potentially very nice HDR photos ruined by this. I've
found no good workaround within the user flow.
Clearly the HDR-output part of the program (which lots of people use
hugin for) is broken and should be fixed :
It appears that the new version uses EXR format internally, and
propagates the bug into the TIFF format output as well. My rectangles
appear WHITE though when viewed in Luminance HDR...
Nona runs with the following from the log file:
"C:/Program Files/Hugin/bin/nona" -r hdr -m EXR_m -o
"DSC_906
hugin is clipping black holes in HDR image (exr) in the shape of masks
(inclusive).

LDR image looks just fine though.

I have exactly the same problem on Ubuntu 10.10 with hugin 2010.0.0.5045
and enblend 4.0-753b534c819d
I tried the tiff ouput workaround. Yet I still have the black
rectangles.
Here is an extract of my .pto file for detailed configuration:
# hugin project file
#hugin_ptoversion 2
p f2 w15000 h136
this is what I'm getting when trying to generate HDR panorama out of 6
.tiff images (see screenshot).

stripe on the bottom of hdr images and complete LDR image.
