I would not use IE either, but some clients do:-(
In the meantime I can give some more infos on the problem:
I can reproduce the crash when I load the same URL twice:
- copy a valid URL to drawmap.php directly to the address bar of IE
>> image loads
- press F5 to reload the same URL
>> IE hangs
So normally in a chameleon app every URL should be unique (that is
what the dummy var is for). However I suppose IE does something
nobody knows about, e.g. call the URL more than once.
The output format of the map seems not to be the cause of all that,
as I guessed before.
I have built a small test application to reproduce the bug:

I will also have to check if maybe apache blocks repeated calls?
