Re: [pygame] Font from file object crashes for me

Hi Brian

Dont know if this helps. I tested in on Mac with Pygame 1.71 and  
Python 2.4.1

When pressing right cursor key arrow the Debug IO windows is  
repeating several times the following text:

['verasans.ttf', 'file:verasans.ttf']
The font object is created only from pygame.font.Font(). Once a
font is created it's size and TTF file cannot be changed. The
Font objects are mainly used to render() text into a new Surface.
The Font objects also have a few states that can be set with
set_underline(bool), set_bold(bool), set_italic(bool). Each of
these functions contains an equivalent get_XXX() routine to find
the current state. There are also many routines to query the
dimensions of the text. The rendering functions work with both
normal python strings, as well as with unicode strings.

opening through file object: verasans.ttf

Then (after several times repeating the message above) I got the  
following error message:

IOError: (24, 'Too many open files', 'verasans.ttf'


That might not solve the problem, but it seems the TTF file wont be  
closed. I asked myself why the error message appears repeating?

Greetings Farai
