SRMs: possibe updates for xulrunner/icedove/kompozer on stable

[Mike Hommey <mh@glandium.org>]

Hi,

In case you don't read my blog, it appears that there were hidden issues
in the mozilla code base on arm, mips, sparc and powerpc.

Question is: should we update the stable packages with the relevant
patches ?

Cheers,

Mike
