Hello!
Can you please give me more information about your build environment.
Is it local or remote?
I guess you can add GDB to the build environment by adding "Requires:
gdb" to RPM spec file.
Also, I suspect the problem isn't related with fonts, because
synfig_icon.sif file doesn't have any text layers.
I wonder, what happens if you try to use synfig to render empty file
(in the build environment).
Best Regards,
K.
