Eh, by normal I mean "documented" I guess :)

Plotting several times in the same figure isn't a problem, even at  
the interpreter. The problem seems to be closing the plot window, and  
issuing a command that tries to communicate with it i.e. using clf()  
will cause a crash as well. I've been able to reproduce this at a  
normal python interpreter with

from pylab import *
ion() # interactive mode, accomplished with -pylab in ipython
plot(arange(0,9),arange(0,9)**2)
# Close the window when the plot appears
plot(arange(0,9),arange(0,9)) # or any other plotting command like clf 
(), I've also tried hist()
