I had the same problem, but not when entering the nether. Instead, it occurred when I went near a certain place on the world map on a multiplayer game: MC 1.4.5 crashed and I was not able to enter the game again without crash. The problem only existed on my PC (64 Bit), but not on my laptop (32bit), which is too slow to play MC. However, I could use my laptop to move the player away from that place. After that, I could play MC on my PC as long as I didn't go to near to that place.
Apart from the hardware, both systems run openSuse Linux 12.1 32/64bit with the newest available java/openJDK 1.6 from the repositories.
When I read the bug report here, I installed java 1.7 from
This package seems to have problems finding it's own libraries, in this case libjawt.so I found it in /usr/lib64/jvm/java-1.7.0-openjdk-1.7.0/jre/lib/amd64/
on the command line, just before starting MC there.
EDIT:
For some reason, java does not recognize the 64bit version of ~/.minecraft/bin/native/liblwjgl64.so.
To solve this, I moved liblwjgl.so to liblwjgl32.so and made a link to the 64bit one by
ln -s ./liblwjgl64.so liblwjgl.so
The other libs in this directory do not need this...
Now, it's running!
So, the summary is: It does not only happen when entering the nether, but also at certain places on the map. My 32Bit system is not affected and the update to openJDK 1.6 solved the problem on my 64Bit system.
Hi!
Just a comment:

http://software.opensuse.org/package/java-1_7_0-openjdk
although it's still said to be unstable there.
This package seems to have problems finding it's own libraries, in this case libjawt.so I found it in /usr/lib64/jvm/java-1.7.0-openjdk-1.7.0/jre/lib/amd64/
and so did
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/jvm/java-1.7.0-openjdk-1.7.0/jre/lib/amd64/
on the command line, just before starting MC there.
