Hi, I would like to nominate issue 119337 ([1]) as show stopper/blocker bug.
It's a regression, Mac only. It was a blocker already, set back to major from marcus, but I see no reason for this. It's fixed on trunk now, patch added to task.
I think it's severe enough for AOO3.4.1 and since it was an API implementation problem more UNO API stuff may be concerned (e.g. draw object im/export uses this API) in the Mac version.
Sincerely,
Armin
