Description of problem:

Some Python software that I've downloaded (a package called 'leo', not
from Red Hat) fails with the following error:

 SystemError: Py_UNICODE and Tcl_UniChar differ in size

A little google-ing reveals that other people have had this problem,
bot with leo and with other software.  


Version-Release number of selected component (if applicable):

Fedora Core 1, tcltk 8.3.5


How reproducible:

Run leo.  Fails 100% of the time.  


Steps to Reproduce:

Install and run "leo" (available from
http://sourceforge.net/projects/leo/ )

  
The problem can be fixed as follows:

get the "tcltk" and "python" SRPMS.  In the tcltk source, find
"tcl.h".  Change the datatype for Tcl_UniChar to be 32 bits, so this:

  typedef unsigned short Tcl_UniChar;

becomes this:

  typedef unsigned long Tcl_UniChar;

then rebuild the entire tcltk and python rpms.  

(I don't know if this is a very *portable* way of fixing the problem,
but it works great for me with Linux on 32-bit Intel.)

Also note:  word is that Python 2.3 and tcltk-8.4.5 fix the problem. 
But it would be nice to have this simple backport to the current
release...)
