[Evolution] defunct process

[Rafael Exposito Sarmiento <exosoftr teleline es>]

Help me please
I'm using evolution, into debian sid, kernel 2.4.22

this is my ps command when I begin evolution
11217 ?        S      0:04 evolution-1.4
11219 ?        S      0:00  \_ evolution-1.4
11220 ?        S      0:00      \_ evolution-1.4
11221 ?        S      0:00      \_ evolution-1.4
11222 ?        S      0:00      \_ evolution-1.4


after that, when I search for new e-mail, I have this
11217 ?        S      0:06 evolution-1.4
11219 ?        S      0:00  \_ evolution-1.4
11220 ?        S      0:00      \_ evolution-1.4
11221 ?        S      0:00      \_ evolution-1.4
11222 ?        S      0:00      \_ evolution-1.4
11231 ?        Z      0:00      \_ [evolution-1.4] <defunct>
11232 ?        S      0:00      \_ evolution-1.4
11233 ?        S      0:00      \_ evolution-1.4
11234 ?        Z      0:00      \_ [evolution-1.4] <defunct>
11235 ?        S      0:00      \_ evolution-1.4
11236 ?        Z      0:00      \_ [evolution-1.4] <defunct>
11237 ?        Z      0:00      \_ [evolution-1.4] <defunct>

Every time I have more defunct process, At the end, my evolution is
closed with segmentation faulty

Any Idea.

I'm sorry my english
Thank's
