image.display can't load font?

[dbb999]

Hello, I'm new to Magick++ and this is minor however I can't figure it out.

I construct an image from a path, works fine. If I call .display() the image displays fine but I get a complaint:

"Magick: Unable to load font (-*-helvetica-medium-r-normal--12-*-*-*-*-*-iso8859-1) [Resource temporarily unavailable]."

Runing imagemagick display on same image from command line works with no errors.


I'm happy to ignore this as it doesn't seem to affect operation at all. Just wondering if I need to setup something and if it might bite me later.

Thanks for any suggestions.

Forgot to add system:

Linux Ubuntu-VB 4.4.0-57-generic #78-Ubuntu SMP Fri Dec 9 23:50:32 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Don't know the exact version of imagemagick / Magick++ but it's the current Ubuntu (built the machine yesterday)
