In Writer, even if I open a readonly document, when I press Ctrl+C on a marked text, LibO create a __DdeLink_NNNN_BBBBBBBBBB. (NNNN ir a random number, I think; BBBBBBBBBB is a number, which is the same for all the documents opened in that session). I tried in Windows version and it does not happen. I also tried on Text boxes or images and I doesn't happend either. Tested on a fresh new install on virtualized Ubuntu 11.10 i386 with all the updates and it doesn't happend.
Thanks for bugreport Please, verify if in last version of LibreOffice still reproducible And in which OS/distro it reproducible?
Just checked against oneiric amd64 & x86; and Windows XP with LibO 3.5.1 This bug no longer exists
Thanks for additional testing Due to last comment, changing status to WorksForMe If problem will appear again, please, change status to Reopened
