Description of problem:
I just found this when examininig /tmp/xses-$USER.XXXXXX:

/etc/kde/env/gpg-agent-startup.sh: line 10: test: too many arguments

Line 10 reads:
>>> if ! test -S ${GPG_SOCKET} -o ! test -O ${GPG_SOCKET} ; then <<<
which is incorrect. The "-o ! test..." is passed to test(1). Did you mean:
>>> if ! test -S ${GPG_SOCKET} -o ! -O ${GPG_SOCKET} ; then <<<
?

Version-Release number of selected component (if applicable):
gnupg2-1.9.22-1.fc5
