Not so for Opera - AFAIK OOo use their own toolkit - not any qt stuff, but opera
uses qt for sure, but I think it's version 3, so removing qt4 should still leave
Opera usable.
In any case, just removing that stuff should still be OK. If something fails,
check the logs and re-install the missing lib.
Btw, You can always check dynamic linking consistency with ldd. Just issue
ldd $(which binary)
where binary stands for any executable you wanna have checked, like opera.
You can check overall linking consistency with something along the lines of
for i in /usr/bin/*; do echo $i; ldd $i | grep "not found"; done 2> /dev/null
That's very primitive, but hopefully still effective ;-) (you might want to
chekc other folders, like /bin /*/sbin /*/local/{bin,sbin}, /*/libexec,
whatever.
