I have an issue with crashing in the arena area, which I've been able to reproduce (far more often than I'd like) in both Windows and Linux, each on a different machine. This crash occurs when sound is enabled and set to OpenAL, and when engaging in combat, and drops back to the launcher. I even went as far as wiping my Mint 12 installation in favor of Ubuntu 12.04 just so I could eliminate anything there as part of the problem (despite it occurring on Windows as well) and with that I got a fresh install of the game as well. Since I can't seem to get any console output from the Windows version, and the error log doesn't contain any useful information, all I have to fall back on is console output from the Linux version. This is where the crash occurs, first spitting out a random number of (maybe a 100 or more) errors pointing to the same line but with different EID's:
Thu Apr 19 11:38:21 2012, <src/client/psclientdr.cpp:223 HandleDeadReckon SEVERE>
Thu Apr 19 11:38:21 2012, Got DR message for unknown entity EID:25709.

Thu Apr 19 11:38:21 2012, Got DR message for unknown entity EID:31189.
and after that, spitting out this error after which it drops back to the launcher:
Thu Apr 19 11:39:22 2012, <src/plugins/common/soundmanager/data.cpp:167 LoadSoundFile SEVERE>
Thu Apr 19 11:39:22 2012, Can't load file 'combat.arena'!
NOTIFY: loading plugin instance for crystalspace.sndsys.renderer.openal
DEBUG: Initializing OpenAL sound system
All I have to do to reproduce this error is log in and attack something in the arena area, although I did manage to attack 1 rat on the first login after updating, but after that the error occurs every time with sound enabled.
I did file a bug report
http://70.32.40.136/flyspray/index.php?do=details&task_id=5579, but I fear there isn't enough useful information in there for a dev to know where to start. The only thing I know is that this bug existed before the most recent updates and I haven't seen anyone else with the same issue, so far anyway.
