SIGSEGV when starting digikam from latest git

[Andrew Goodbody]

0.27 was only released on 20th December 2018, it has not got into most 
distributions yet and certainly not into Debian so far. Sigh. Where 
possible it is much more convenient to use distribution packaged 
versions of libraries etc.
