This happens to me as of now - it's been going on for a while. Software
versions:
(andrey)eastein@talisker ~/git/andrey :) $ apt-show-versions |egrep
'gedit|libibus'
gedit:amd64/utopic 3.10.4-0ubuntu6 uptodate
gedit-common:all/utopic 3.10.4-0ubuntu6 uptodate
libibus-1.0-5:amd64/utopic
I get this on Gentoo amd64. SSH_AUTH_SOCK=0 workaround works fine.
Just weird, I don't recall wanting this feature in SSH and there
doesn't seem to be an option to make it not do this.
