Gimp slow startup fonts issue

Has anyone figured out a simple solution to this annoying problem loading the open-source photo editing app Gimp? The startup message is something like: Wait for fonts to load, this can take a while

And it does. A real long while.

Elsewhere on the net folks say it's a fonts cache problem. One Windows user reports a solution by deleting the fonts cache file and letting it rebuild the next time you start Gimp. In that case, it's a one-time problem – once repaired the app starts in mere seconds.

Come on fellow mac hackers, let's not be defeated by Windows users. Can someone find a solution, please?
