I was importing some maps from UT2003 into 2004. From what I heard it should
work just fine and it worked with all but one.

If I copy CTF-DE-LavaGiant2 from the original Digital Extremes bonus pack to the
Maps folder the following happens.

First startup after copying the map:
------
$ ut2004
Exporting CTF-DE-LavaGiant2.....Successful!
WARNING: ALC_EXT_capture is subject to change!
------

Game launches fine and the map works.

Exit and restart again:
------
$ ut2004
Exporting AS-Convoy.....Successful!
Exporting AS-FallenCity.....Successful!

[...] Every existing map seems to get exported now.

Exporting TUT-DOM2.....Successful!
Exporting TUT-ONS.....Successful!
Exporting CTF-DE-LavaGiant2.....Successful!
WARNING: ALC_EXT_capture is subject to change!

History:

Exiting due to error
------

The game leaves a file CacheRecords.ucl in ~/.ut2004/System that was not there
after the previous launch and it doesn't seem to start anymore until I delete
that file and the map from System/Maps.

It seems like a pretty weird error that "set video mode" fails. I'll attach the
logs from first and second launch. They don't really contain many useful things
afaict.

I'm using Nvidia's 5336 drivers, but if that's a driver bug, it's pretty weird.
