I just deleted it here.  However, do note that if you're using kmail, 
it's possible part of that is kmail index.  But in any case, if it's 
needed, it should be recreated, so worst-case it might make accessing 
something a bit slower for a bit.

If you're concerned, try the rename trick.  Just move/rename the file or 
directory to something else, and use your computer as normal for a few 
days (including at least one kde restart).  If you've not noticed any 
problem traceable to that after a few days and at least one kde restart, 
and in particular if the files haven't been recreated, final deletion 
shouldn't be an issue.

FWIW (noting that you're a gentooer also), that's one reason I don't want 
semantic-desktop back on my system.  I don't like "surprises" of several 
gigabytes (and I had several of them back when I /did/ have USE=semantic-
desktop) for something I don't find useful in the first place.  But of 
course gentoo/kde is (build-time) force-enabling semantic-desktop with 
4.11 (tho it's still run-time disablable), taking away the previous 
choice to not even install the (for me) junk in the first place.  Thus my 
thread on the gentoo-desktop list asking if anyone else is interested in 
helping me maintain the patches I'm already using with the 4.11 betas, to 
keep the junk off the system despite gentoo/kde's hard-enabling it at
