error: Package has no %description: mandelbulber

[PabloTwo]

That error is what I get when I try building from the spec file. When I check the spec file with rpmlint, it's:
mandelbulber.spec: E: specfile-error error: Package has no %description: mandelbulber
mandelbulber.spec: E: specfile-error error: query of specfile mandelbulber.spec failed, can't parse
0 packages and 1 specfiles checked; 2 errors, 0 warnings
Well, the package does have a %description section. I've retyped it, I've removed it and replaced it with the %description section from other spec files that rpmlint has no complaint with, yet, it's always the same error. I've looked for typo's or any critical missing bits top to bottom and compared this spec file with other spec files blessed by rpmlint until my eyes are about to bleed.

Does anyone spot anything I'm blatantly missing here?

I finally resorted to just typing in the entire spec file from scratch by hand instead of starting out with the basic template generated by the rpmdev-newspec command, with only a very few minor differences from the spec file I posted above. This time, rpmlint had no issues with a missing %description section. The package built just fine. I'll never really know exactly what causing the original issue.
