This gives more evidence, that firefox may easily crash a low memory 
(64MB) xserver:
"The problem may be related to some programs caching things like 
bitmaps in the x-server. Can you see a relation to the programs you are 
using and the amount of memory X is using?"

The example page given below is a good test case because firefox has to 
load big image files (e.g. 2592x1944) which are downscaled to 350x230. 
- If firefox does cache bitmaps in the X-Server it would obviously need 
additional RAM on the LSTP client.

On my laptop (not ltsp) Xorg takes another 10 MB RAM when opening 
section "Bilder" on alp-tschingla.ch.
