Server won't accept "foreign" maps

[Raven]

System: Dual xeon 2.4 / 3GB DDR ECC
OS: Ubuntu 8.04 Server (Commandline only)
Nexuiz version: 2.4.2
Executable: nexuiz-linux-686-dedicated

I'm getting this error when I try to create a server when there are custom maps in the data-folder:

"Host_Error: server: Program error in function MapInfo_Get_ByName:
... but I just wrote it!"

My (physical) server was down, so when it came back up I figured before restarting my nexuiz servers it was as good a time as any to enfridge some security on my nexuiz installation. This so I can give my clan some access to upload their favourite maps without them screwing up the stuff that's already there. So I played around with access-rights/chmod for that purpose, but somehow I screwed up and decided to start all over. I backed up the current installation through FTP, removed the directory and created a new one and assigned it full rights to user "nexuiz". I then logged in as "nexuiz" and downloaded/unzipped nexuiz2.4.2 from sourceforge.

Then I needed to get back my startup scripts from the backup I made earlier.

Chmodded them to u=rwx (and later even a=rwx) > Start my script -> Works fine.
Shut down the server > uploaded my server cfg's > restarted the server -> Fine!
Shut down the server > uploaded my maps > restarted the server -> Crash!
Remove the maps > startup the server -> Fine!

The tts-mod pk3 had no influence whatsoever. Wether it's there or it's gone, it still crashes when there are custom maps in the data-directory.
My scripts are just copies of the example script. All they do is call different cfg's, 1 for 1on1 and 1 for the normal DM server.

Directory-info nexuiz-rootdir and the data-dir: http://pastebin.com/m634002e7

I don't get it! I've been trying out stuff for like an hour, but I can't get it to run again with custom maps. I would like to continue to use 2.4.2. I'm running Instagib servers, and although you people did a wonderful job on 2.5 and 2.5.1, it just doesn't feel right playing minsta on 2.5.1 :/ It's probably something really stupid, so I really hope you guys can help me out here.

[Edit] Now they seem to crash after a certain amount of time running as a background service. This is what my console displays: http://pastebin.com/m4387c80b
I really gotta go now, I'll take a look at the logs (if any) tomorrow...

anyone?

I personaly think you would be better off applying 2.4.2 physics to a 2.5.1 server than remaining with a 2.4.2 server.

It is my guess that the maps you are trying to use don't work with 2.4.2, but I lack expertise in that area. You should probably find somebody to confirm.

These maps are the same I used before.
Anyways, how do I apply 2.4.2 physics to a 2.5.1 server? Will it have the same feel and sounds?

Sadly, I do not have a 2.4.2 physics cfg for you to use.

It would have 2.5.1 sounds and models, but also have the same movement and weapon physics of 2.4.2. =/
