I fired up my little 32-bit netbook this morning to update it, and now I see the chromium "aw snap" problem is here too. So, the good news is, you do not necessarily have anything wrong with your system or configuration, but the bad news is, the 32-bit chromium package is defective. I assume, since the 64-bit packages is OK, that this is a packaging problem of some kind. Meanwhle, there's always iceweasel or the other browsers.
