Catching stderr output from graphical apps

[gry at ll.mit.edu]

Python 2.3.3, Tkinter.__version__'$Revision: 1.177 $'

Hmm, the error window pops up with appropriate title, but contains no
text.
I stuck an unbuffered write to a log file in ErrorPipe.write and got
only one line: Traceback (most recent call last):$

Any idea what's wrong?
