REVISION SUMMARY
  Don't create `KUser()` instance just for an example text in "What's This" mode.
  When logged in via LDAP this can create quite some delay until the dialog opens.

TEST PLAN
  Dialog opens quicker now, even on local login it spends 1ms in there for no real gain.

REPOSITORY
  R241 KIO
