500 error and gd warning in error logs

[GoogleCodeExporter]

What steps will reproduce the problem?
1. login
2. I get a 500 error
3. in /var/log/apache/error.log I see a bunch of "gd warning: one parameter to 
a memory allocation multiplication is negative or zero, failing operation 
gracefully"

What is the expected output? What do you see instead?

a working page

What version of the product are you using? On what operating system?

Please provide any additional information below.

had the very same problem this morning (after months of running fine)
cache.iconcaching = 0 do fix the issue but doesn't resolve it

would be good to know what cause it
i know icon caching has always been a bit buggy for me, there might be 
something to investigate
