Would the conflict go away if the rdeps of qt-webkit (these browsers)
still had a use dep on gstreamer? IE, do these browsers tend to be
installed even though the user's installed/installing chromium ?

How much Gnome stuff needs qt-webkit? I figured that gnome stuffs
would be much more likely to require webkit-gtk , yes?

So a KDE user, with USE="-gstreamer" , is most likely not going to run
into this issue yes? And Gnome users that have webkit-gtk[gstreamer]
packages don't run into this issue with chromium anyways, right?

(i know there's always overlap as anyone can install anything, but i'm
thinking of the general scope of impact here)

None.

Indeed.

Correct.

A KDE user with -gstreamer -icu set, should not have problems. But
once gstreamer is set for HTML5 audio/video support (which qt-webkit
enables by default on users request), the problem with -icu blocking
chromium appears. I still have no idea how many Qt (including KDE)
users also want chromium though.

For the time being we have decided to leave the useflag defaults as-is.

I have added a new part to our FAQ on the wiki, so users can be pointed to that:

http://wiki.gentoo.org/wiki/Qt/FAQ#qt-webkit_vs_chromium_block_because_of_icu
