How can I remove lost files to prevent recovery attempts

Each time I try to start up Libreoffice it wants to recover some old and obsolete files. When I click the discard button and then confirm discard LO immediately shuts down. see below

peter@linux-byce:~> libreoffice
qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 1153, resource id: 35651682, major code: 40 (TranslateCoords), minor code: 0
QPaintDevice: Cannot destroy paint device that is being painted

When I start with the option norecover everything works fine. I would love to delete the offending files if I knew where to look for them.
My OS is opensuse tumbleweed.

You could get the file names using grep "/org.openoffice.Office.Recovery/RecoveryList" $HOME/.config/libreoffice/4/user/registrymodifications.xcu but from my perspective, due to Discard not working, it is more likely that your user profile is corrupt.

PS: I don’t think that the error message got anything to do with your problem.
