I just got this when doing print 10xx10000. Sometimes it crashes the first time I resize the terminal, sometimes I need to resize it a few times quickly. If you send me a note I can email you the error I get when it crashes.
I assume you're using an up-to-date version of bpython ? I remember dealing with this kind of stuff a lot in the past (curses is terrible at this kind of thing) and I had considered it fixed, so please do send us bug reports if possible.
