convert segfaults on unsharp

[Dariusz J. Garbowski]

Hi,

Does anybody else see it as well? Google didn't show much...
Should I bugzilla it?

convert segfault on my Fedora 7 when using unsharp with radius 
parameters being 1.2, 1.4, 1.6, 1.7, but not with anything =< 1.0 and 
not with 2 and 4.

Example run:

$ convert -unsharp 1.6x1.4+0.6+0 input.jpg output.jpg
Segmentation fault


ImageMagick 6.3.2.9-3.fc7




When more complex command was run from a script:
