Thanks Kurt. I can't find those two specific LORs in the list on that page. The page also says to report them using a link, which leads to 404 :-), or on this mailing list, which I did. I am not sure what else should I do. How do I know if I have got a backtrace? Are those errors: pid 43297 (conftest), jid 5, uid 0: exited on signal 11 related or it's a different issue? GrzegorzJ
