For comparison, here's the list of packages that would be pulled in if I were 
to rebuild kdeutils-meta with cups:

gnome-base/gnome-common-3.7.4
dev-python/pycurl-7.19.0-r3
x11-libs/xpyb-1.3.1-r2
dev-python/pycairo-1.10.0-r4
dev-python/pygobject-3.8.3
app-text/xmlto-0.0.24-r1
dev-python/dbus-python-1.2.0
dev-python/pycups-1.9.63
app-admin/system-config-printer-common-1.4.3
app-admin/system-config-printer-gnome-1.4.3
kde-base/print-manager-4.11.2
kde-base/kdeutils-meta-4.11.2

No mention of strigi-analyzer or gtk+. Strigi-analyzer isn't installed here 
because nothing depends on it. As for gtk+ :

Don't ask me why equery is ignoring the version specifier in the command line. 
As far as I can see, the only packages that should be in that list are librsvg 
and libnotify, both of which only require gtk+:3 if the test USE flag is set, 
which it isn't here. Oh, and bluefish, which seems to need gtk+:3 for its 
printing, which I don't use; and libreoffice, which only pulls it in if you've 
asked for it specifically by setting the gtk3 USE flag.

So it seems to me that you're safe. You could always run revdep-rebuild after 
letting all those packages be stripped out, just to make sure.

HTH.
