How cute and beautiful! (NOT!) :-)

But well, if that's not considered a problem by you Qt guys, then I
guess we just have to add a workaround on symbian and keep the
versions as they are. Please make sure that every library which gets
decoupled from Qt (my understanding is that QtWebKit is the first)
follows the same policy.
