This may/may not be related to Kunami's report. It died for me in the Second Tutorial Campaign, but I had been playing for a good 45 minutes before it went.
I have put in the Widelands debug version (using the build changes method detailed on http://wiki.ubuntu.com/DebuggingProgramCrash), which I also recommend to Kunami. ** Attachment added: "Crash report with stacktrace" http://librarian.launchpad.net/5787341/_usr_games_widelands.wu3qEl.crash -- a crash in tutorial campaign https://launchpad.net/bugs/74757 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
