I can't see anything replacing cStringIO with StringIO. It is easy
enough to check anyway:
Python 2.5.2 (r252:60911, Jan 4 2009, 17:40:26)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cStringIO
>>> type(cStringIO.StringIO)
<type 'builtin_function_or_method'>

Sorry ssteiner, it was an incomplete mail.... added to my nasty english...
I want to say that i haven't seen this tutorial and i like it much, i've
seen many tutorials of how to make -how to make animations, collissions,
movements...- a game but not about to how to develop -programmatically, with
patterns- a game...

Does this mean that you are offering one? I'd love to read a tutorial on how to build a GOOD and NICE game.

Maybe seeing how wacom tablets are usable in pygame would help?

Maybe my cStringIO has been transparently replaced by StringIO for
some reason. I would think that cStringIO would be available on this
platform but perhaps not.

Strange. cStringIO works for me. I have localized the problem to the
first call to the file like object's tell method. But since this is the
first method called, it might not be limited to it.

cStringIO seems to have the same problem for me.
It is already using open with 'rb'.
Thanks for all your help, I will await the next version / patch I guess.

Hi Bryce,
Try using cStringIO instead. And make sure to open the file 'rb' (this
won't matter on Linux, but will on Windows). I reproduced your problem
with a modified pygame.examples.fonty, and yes, it appears to be a bug.
StringIO instances should work.

Okay:
I wrote the string (self.parts['font']) out to a temporary file and
diff'd it against the original file, and they are identical.
Pygame successfully loads the font from the temporary file, and the
font works normally. However I would definitely like to
find a less kludgish solution to the problem.

Pygame should be supporting a file-like object no problem, so this seems
like it could be a bug.
Can you be more specific on when in the past it worked, and what happened
between then and when it segfaults now?
Also, it's not clear from your problem description whether the problem is
that pygame crashes when loading from a file-like object, or if pygame

This is a guess, but maybe pygame assumes the object passed to Font is
a real file object? If so there's a bug there that it doesn't type-
check and throw an exception, if not it seems like there's a bug there
that it blows up rather than throwing an exception, but that may be
something outside of the pygame code anyway.

The font in question is a custom font in a game data archive. I'm not
sure if by "load the font itself" you mean using sysfont to find it or
use pygame to open the ttf file, but it's impossible in either case,
unfortunately.

Why not just let Pygame load the font itself?
