I see too big problems here,

The most immediate one is all the segfaults from all the different 
programs.. That just screams bad memory to me.  You should first and 
foremost boot from a CD (The Ubuntu install CD will do) and choose the 
Memory Test option.  If you're computer is spitting out errors in this 
test, that needs to be repaired above all else.)

The second problem is the Out of memory error messages.  This could 
happen if one misbehaving program went nuts and used up all available 
memory in your system. (and all the OOM killing would explain why your 
system went nuts.).  However, it can also mean that you don't have 
enough SWAP space and are running out of memory from regular load.

Try the free command from a console and examine the output from that to 
determine how much memory you have (real and virtual) and what you're using.
