Ubuntu – GoldenDict error while loading

dependenciesgoldendictshared library

I installed goldendict, but when I tried to run it the terminal tells me:

goldendict: error while loading shared libraries: libQt5Svg.so.5: cannot open shared object file: No such file or directory". 

I checked that libqt5svg5 and libqt5svg5-dev are both installed. How to solve the problem?
The output of apt-cache policy goldendict is

goldendict:
Installed: 1.5.0~rc2+git20170908+ds-1

and I don't have Qt-related PPAs.
