I can't reproduce this.  Does it depend on the image?  Sure you're not just
running out of memory or something? (your script does take all of the data
in that image and start flinging it around, which of course is not what you
wanted to do).

Not at all: it's a *feature* that you can access the raw data in an image
this way, by using it as a container.  But the icon property take a number
(an id), not the raw data (else, it'd be horribly inefficient because you'd
have duplicate copies of all the image data around in each button that
uses the icon).

If it crashes, it's a bug and should be reported.  But be sure to include a
stack example where clicking on a button causes the crash: I suspect
that there's something else going on here than what your original diagnosis
would indicate.
