FOSS gamedev and creative worlds

Whenever i go into a world with mods (even a server with mods) the game crashes, it wont let me go back into the game, the window loads, but i cant see the menu. However when i load a world without mods, the game does not crash, it just lets me play as usual. My specs are:
OS: Linux Lite 1.0.6
Graphics Card: 256MB NVIDIA Corporation NV34 [GeForce XF 5500] (rev a1)
Memory: (Total) 1543400 kB
Free Memory: 851844 kB
1 and a half GB's of RAM

Any help?

We need the content of debug.txt, create it as described here: https://forum.minetest.net/viewtopic.php?id=5073

These are the only lines in debug.txt, they are error ones. the rest of debug.txt is completely blank:
12:55:23: ERROR[main]: generateImage(): Could not load image "unknown_block.png" while building texture
12:55:23: ERROR[main]: generateImage(): Creating a dummy image for "unknown_block.png"

This happens when connecting to Redcrab's server, i am using the latest git, with the new sounds.

Is anyone else having this problem? I am thinking it may be a problem with my minetest copy.
My graphics card is not the problem, it is a very good card, no graphics problems at all with minetest or any other game.
It will handle all of the fancy features (Except shaders) perfectly, even with Enabled Full Range Viewing on with no lag.

I'm on red crabs server and the same thing happens to me. But it does not crash my game.

Well, that happens to me when I log on to there with the latest git (it doesn't crash the geame though), but I usually use 0.4.5 for playing on redcarb's server.

This is why Redcrab need's to update his server to 0.4.7

Could anyone else help me with this problem?
I think that it may be a problem with Redcrabs server itself.

You should maybe just use an older version. That's it.
