Hmm... I suppose this is valid, although it does seem a bit of a strech to
call the graphics linked to the openSSL library, it does seem to be
basically the case.

That is definately possible. the LGPL is a good choice here if a copyleft on
the images is highly desired. (Obviously the LGPL is compatible with GPL
linking exceptions). Otherwise, I would suggest the Expat licence.

That would certainly work. There is definately no need for the icons to be
the OpenSSL library. There is no problems with a GPL'ed program using
non-GPLed graphics file, or a non-gpl program using GPL'ed graphics files
(although admittedly some people would not be happy about this). So
certainly there is no need to worry about possible licence conflicts in this
