Hello Adrian,

there is an patch in upstream HG that fixes this, I habe vcherrypicked
it in GIT.

However hugin currently FTBFS due to the openexr/imath breakage
(#1144763 - Thanks for your NMU). I have tried building hugin against
the pending NMU openxer version but it fails with:

[ 22%] Linking CXX executable celeste_standalone
cd /tmp/HUGIN/hugin/obj-x86_64-linux-gnu/src/celeste && /usr/bin/cmake -E cmake_link_script CMakeFiles/celeste_standalone.dir/link.txt --verbose=1
/usr/bin/x86_64-linux-gnu-ld.bfd: /usr/lib/x86_64-linux-gnu/libvigraimpex.so: undefined reference to `Imf_3_4::Header::Header(Imath_3_1::Box<Imath_3_1::Vec2<int> > const&, Imath_3_1::Box<Imath_3_1::Vec2<int> > const&, float, Imath_3_1::Vec2<float> const&, float, Imf_3_4::LineOrder, Imf_3_4::Compression)'
collect2: error: ld returned 1 exit status

Rebuilding libvigraimpex against the new openexr let the hugin build
succeed.
