I've tried to reproduce the build failure, and I got a little different
results than above, so I'm sharing them in the hope they benefit in
tracking down the bug.
---- Unmodified package ----
I tried apt-get source digikam, followed by
sbuild --dist unstable digikam_4.4.0-1.1.dsc
It ran for a while, and then failed with the following message:
make: *** No rule to make target '/usr/lib/libsoprano.so', needed by

---- With libsoprano-dev in Build-Depends: ----
For testing purposes, I added "libsoprano-dev" (which contains this
file) to build-depends and created a new source package (Please ignore
the incremented version number), and got a different failure:
CMakeFiles/kface.dir/detection/opencvfacedetector.cpp.o: In function
`KFaceIface::Cascade::Cascade(QStringList const&, QString const&)':
undefined reference to `cv::CascadeClassifier::load(std::__cxx11
::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)

I hope this helps in getting Digikam to run again. To me, the second
failure looks like cv needs a rebuild to expose the new __cxx11 symbols,
before digikam can compile cleanly with GCC5.
However, I don't know how to request that, or check whether it has
already been requested.
