ZOMBIE iceweasel and icedove simultaneously !

[knp]

Hi

Iceweasel and Icedove became ZOMBIE simultaneously (knoppix 7.2).
Impossible to get them again even by killing the processes with the knoppix tools give in "the Knoppix/SystemTools" .

I was obliged to restart my laptop. Does somebody understand the probable origin of the problem?

(Necessarily relied to a certain common "mozilla configuration"?).

Thanks
