SIGSEGV when starting digikam from latest git

[Gilles Caulier]

Hi,

>at /usr/lib/x86_64-linux-gnu/libexiv2.so.26

This crash appear in libexiv2 0.26. Even if digiKam can compile and run
with this version, we recommend to use last one 0.27 which come after 2
years of development and plenty of bug fixes.

Best
