Missing Text in Air Application Flex4+Mac OSX Snow Leopard

I am running the same AIR application under windows, linux and Mac OSX Windows and Linux look fine, but under mac OS-X the controls are not showing any text. Button, Tooltips, Labels, Check boxes, everything is blank.

I just ported that app to Flex 4. Flex 3 versions of the same app on the same OSX machine works.

How can I get controls to show text under Max OS开发者_运维问答X?

Is this a font problem?

I had the same issue when I migrated a user account from another machine into Snow Leopard. The solution seems to be to erase the fonts in ~/Library/Fonts (note that this is the USER font directory, not the system's):

This seems to be an issue specific to this Mac computer.
I will close the question since it won't really benefit anybody.
