ANYBODY WANNA BUY A UN55 BOTTOM BRACKET??
Gulp, I hope I was right!
Seriously, though, it's hard to think of what else it might be, and this is the first thing I would try. Judging by your bike list, I presume you've had this bike since new, and that it hasn't sustained any damage to the BB shell? Also, do you happen to still have the old UN72, and can you compare the length of the two cartridges?
