Build hangs

[Robinlovelace]

Thanks for a great docker container. Unfortunately I cannot get it working using the following command, for example:

 sudo ./run-qgis-2.14ltr-in-docker.sh 

I get loads of output then it hangs with this message:

/usr/lib/libqgis_core.so.2.18.17(_ZN9QgsLogger16logMessageToFileERK7QString+0x72)[0x7f6f13ec6632]

Tried in both the 2.18 and 2.14 folders. Context: I'm working with @jannes-m on an open source book titled Geocomputation with R. Dockerisation would be great for reproducibility and testing and help others access the power of QGIS.
