Description:
when using both the tkinter GUI and the locale.setlocale
(locale.LC_ALL, '') call on Py2.4, the following error is 
printed to stderr:

<pre>error reading package index 
file /usr/share/tcl/vfs1.3/pkgIndex.tcl:
syntax error in expression "[package provide Tcl] < 8.4": 
extra tokens at
end of expression
</pre>

in addition to this, the BackSpace key appears not to be 
handled by the tk input widgets (for example "Entry") 
after the setlocale call.

in Py2.4.1 the error is no longer printed, though the 
problem with the BS key persists.


Testcase: 
see attached file.
