Thanks for the alert.  Are you using python2.3?  I've heard that 2.3
generates deprecation warnings and I plan to get them cleaned up in
the near future and do a bug-fix release, probably 0.21.

Looks like you passed an integer to a text label command in the
set(gca..., command that is causing your troubles.  If you are trying
to set a ticklabel, note that they must be strings, not ints.  Eg,

  set(gca(), 'xticklabels', ['%d' % val for val in arange(8)])

not

  set(gca(), 'xticklabels', arange(8))


Is this the source of your troubles (The example code you meant to
send didn't come through)?  Check it out.  If not, send me the script
that generates the error and I'll take a look.  I haven't seen this
bug before (and I use the library a lot <wink>).
