smooth() = breaky breaky

Can someone explain how turning on smooth() could actually break an applet that runs fine without it?
I don't want to post the code example because it is very sloppy so that might very well be the problem. In general, I am placing box()s in a spherical configuration. There are a few line elements as well. It runs fine without any smoothing. But once I turn smooth() on, I get an ArrayIndexOutOfBoundsException error.
Is there something going on with smooth behind the scenes that would cause something like this to happen?

because smoothing works by averaging neighbouring pixels (in very general terms!) that it somehow tries to access pixels outside the buffer, hence the exception. never encountered this before, so if you could post some code (or send it offlist) i can have a lüük  fanx!

if you're using textures, there's an annoying bug in that code that causes trouble when smooth() is turned on. i thought it had been fixed, but apparently there were two bugs in the same dozen lines of code 
this will be a moot point once we get the new graphics code from sami and carlos (probably release 58 ) but i'll try to trap the problem for 57.
actually, if you could send the sketch folder (zipped up) to me (fry at media dot mit dot edu) i'd be most grateful, and i could try to track down specifically what it's doing or where it's dying, i can trap that for 57 (coming very soon).

flight404 sent the code offline, so i've just finished a fix that will be in 0057.
