+Subject: [PATCH] desktop: do not complain about soffice command line options:
+
+These are handled in the soffice wrapper script, but that is too stupid
+to be able to filter these out, so just ignore them in soffice.bin.
+
+(regression from 4efbd87e31e7488dfcdd1d07ff979f1f59b8b1f1)
+
+Also, print errors on stderr.
