build from master (update around 23:00 2011-08-09), - start writer document - type bla bla - copy bla - go to new line - paste > no bla - start 3.4.2 writer doc - paste > bla
*cough* I broke this a few days ago, fixed it earlier today http://cgit.freedesktop.org/libreoffice/core/commit/?id=20edd9cfbd865a087f8735a647b9cf3c2fbd22b5
As an aside, a good thing to do here on reporting "master" bugs is to cut and paste the build id from help about.
You said "paste"... Hmm, does work here ;-) LibreOffice 3.5.0 Build ID: a81389f-4eb4f62-efab8f6 thanks, also for this tip.
*ha ha*, yeah, indeed. "paste doesn't work->please paste in build id", luckily our copy/paste-source works, its the paste/paste-dest that fails.
