OpenType support missing for "Ubuntu", script 16

[Peter Passchier]

Ubuntu 18.04.1
OpenLP from standard repo (2.4.6-1)
LibreOffice from standard repo (6.0.6-0ubuntu0.18.04.1)
When starting openlp from a terminal, the message that comes up is:
`OpenType support missing for "Ubuntu", script 16`

Further messages:
```
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
javaldx: Could not find a Java Runtime Environment!
Please ensure that a JVM and the package libreoffice-java-common
is installed.
If it is already installed then try removing ~/.libreoffice/3/user/config/javasettings_Linux_*.xml
Warning: failed to read path from javaldx
```

(I went with the Thai interface, and imported everything, but the message happened before that.)

Besides the warnings printed, was there something not working in OpenLP?
And if so, what exact package did you install to resolve the issue?

[Peter Passchier (peter-passchier)]

I didn't look extensively, but it seemed to work. I haven't been able to resolve this, I was assuming a package should have been pulled in that didn't, and I was hoping to learn what other package I need to install manually to resolve it. There are so many Ubuntu packages with OpenType in their description... Which one(s) do you have installed (assuming you don't get this)?

None of those messages have anything to do with OpenLP directly. None of them makes any difference to running OpenLP.
