On 3.2 M5 and prior (tested on 3.1.2), Eclipse crashes when running a large Swing based JDT project and font antialiasing is turned off.

On Kubuntu 5.10, when turning off font antialiasing in the KDE control panel either completely or by specifying a font size range, Eclipse crashes upon start of a large Swing project with:

The program 'Eclipse' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
  (Details: serial 51794 error_code 16 request_code 36 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Eclipse 3.1.2 reported no error at all, just crashes. This problem tuns up with different xorg drivers, either ATI proprietary or the free ati/radeon driver.

I tracked it down to the settings in .fonts.conf (see attached file). If the settings for excluding font sizes from antialiasing is commented in, Eclipse crashes.
