Mac OS X: Fix possible crash when using some TrueType fonts. 

This is just a workaround. We simply avoid removing the custom font
(intentionally leak it, a small price to pay) because otherwise it will
invalidate Qt's font cache, which in turns trigger the crash at
CoreText's CTFontCopyGraphicsFont.
