[Qgis-user] [QGIS-Server 3] Labels show as squares

[Bernhard Ströbl]

Hi,

I am facing the following issue with QGIS-Server 3: All my labels are 
shown as black squares (one square for each letter).
First the reason seemed to be the path the application was looking for 
fonts as lots of messages "QFontDatabase: Cannot find font directory 
/usr/lib/x86_64-linux-gnu/fonts" got thrown.
The fonts are installed in /usr/share/fonts so I added a symlink as a 
workaround, now the messages are gone but the labels are still squares.
Any hint what I am missing?

BTW: How can I convince Qt to simply use the system fonts and not look 
in /usr/lib/x86_64-linux-gnu/fonts?

System: QGIS-Server 3.0.3 on Debian Stretch (dockerized, Image: 
php:7-apache)

regards
Bernhard
