I'm on RPi4 arch armv7l using LXDE desktop. Recently I upgraded my system and went from libreoffice-fresh-7.1.5-1 to7.2.0-2. As soon as I open a document or even create an new document, a libreoffice document recovery dialog pops up, asking to recover the document. If I choose to do so, after pressing "finish" the document recovery dialog pops up again. This keeps on going until you choose not to recover. But then, as soon as you want to open a document or create a new document the document recovery loop starts again.
I already completely removed libreoffice-fresh using pacman -Rns, removed the ~/.config/libreoffice directory and installed libreoffice-fresh again but the problem remains. On 2 other RPi4's and 1 RPi3, also armv7 and LXDE desktop, libreoffice-fresh 7.2.0-1 is installed and they have the same issue. There are no libreoffice entries in the journal.
I downgraded all RPi's to libreoffice-fresh 7.1.5-1 (I don't have 7.1.5-2 in pacman cache) and then libreoffice works normal. I seems like the error is introduced in libreoffice-fresh 7.2, at least on armv7 architecture.
