Comment 3 for bug 1749224

> When I wait a couple seconds before I login again everything is fine. It is just this quick logout/login cycle which stops plank resp. bamfdaemon.

That suggested a work-around that - hallelujah! - seems to work. To wit: set plank to autostart, for all graphical user accounts, _with a delay_. Five seconds works for me.

I'll cross-post this comment - in an 'issue' - of its own, to Ubuntu's Plank repository, even though I am on Mint. For, who knows, perhaps bugs posted there actually get fixed? (In this _repository_, all or at least nearly all bug reports languish for years without attention from the maintainer. If there still _is_ a maintainer.)
