No Fonts installed on this device

[darzid]

I ran into this exception when trying to generate a PDF on Linux, CentOS 7. Initially I thought I ran into issue #125, and hoped to resolve it by upgrading from v.1.2.11 to v1.2.12.

However, v1.2.12 still raised the same exception: No Fonts installed on this device!

I've tried the following:

1. After reading issue #125, I looked into my etc/fonts/fonts.conf file, to determine where fonts could be located on this Linux server. The fonts.conf file included ~/.fonts. Because I had read/write access to that directory, I copied a single .ttf file into ~/.fonts. Still I got the same message. This rules out the "non recursive folder search" (as described in #125) as the root cause for my problem.
2. I downgraded to v1.2.6, the version that didn't have the issue reported in #125. However, 1.2.6 gave another exception: "Could not find a part of the path '/usr/share/fonts/truetype'."

So I reverted that downgrade, because it didn't solve my problem. Based on my findings, the exception message is the same as #125, but has another root cause. If there's anything I can check on my CentOS 7 system, let me know.
