I see. We can solve it locally like checking the pointer and if it is 0 then
creating a new FontPlatformData object. If it is a unique situation then it
would be enough. If it is just an example of how can bad happens then we must
find a more general solution. I guess it can be unique because the patch worked
form me (I could browse with QtLauncher without segfault after applied it).
I see two possibilities: 1. introduce a macro like USE_FONTCACHE and add
#ifdef-s when it is necessary
     2. implement a FontCache that provides the needed interface without
leaking

So, what do you prefer? Local solution, one of the two above, or something
else?
Anyway, I think we must not return with a pointer of a newly created and
instantly released object from methods of FontCache.
