Here's some update with the 2nd beta build. On my previous install
(Ubuntu 9.10 x64), Aquaria segfaults right after the loading progress
I installed Ubuntu 10.04 i386 and Aquaria worked just fine (I didn't
play long, just checked it wasn't segfaulting anymore). Then I wanted
to try Alien Arena 7.33 which didn't work on Karmic and also uses OpenAL.
Alien Arena doesn't ship with libopenal so I had to install it from
the repos. After fixing /etc/openal/alsoft.conf to use pulse audio, I
got Alien Arena working alright.

Then I wanted to test Aquaria some more. Bam. Segfault right after
loading screen just like in Karmic . So I removed the libopenal, and
it wasn't enough. I had to rm -r /etc/openal to get Aquaria working
again (I could have also purged the package).
I don't know what's wrong with Ubuntu's OpenAL since 9.10 but it's
clearly messed up... At least with my chipset.

Another thing, totally unrelated, after playing a while the
screensaver activated, crashing the game and forcing me to kill it in
a TTY to be able to use my machine again. I had to run
gnome-screensaver-command -i to keep the screensaver from going on to
be able to play.

Once I got that right (no openal package installed and screensaver
inhibited), Aquaria was running perfectly.

Could someone else on the mailing list confirm these bugs ?
