New submission from Stephen P. Schaefer:
The following fails with python 2.5 as built by Fedora 7:
t2.py:
import sys, Tkinter
Tkinter.Button(text=u"").pack( )
Tkinter.mainloop( )
$ python t2.py
python: ./Modules/_tkinter.c:941: AsObj: Assertion `size < size *
sizeof(Tcl_UniChar)' failed.
Aborted
The following patch corrects the problem:
