item name mixed up in the message log

[ghost]

Sometimes, the game mix up the name of an object in your inventory with another. It doesn't affect gameplay, just the message log. Here is an example: I'm wielding a pick axe (slot v) and my alternate weapon is a quaterstaff (slot a). I tap Alt and here is what is displayed in the log:

a - a blessed +1 quarterstaff (weapon in hands).
v - a yellowish brown gem (alternate weapon; not wielded).

Surprised, I tap Alt again to double check and the bug is gone:

v - a pick-axe (weapon in hand).
a - a blessed +1 quarterstaff (alternate weapon; not wielded).

The yellowish brown gem is actually in slot w, so just after the pick-axe. Maybe it's an hint, or maybe a coincidence, I can't tell.

This bug is completely random, it happened to me a few times, but I have no idea how to reproduce it reliably. I also remember that the first time it happened to me only the class of the item was wrong, not it's attribute. I can't remember the specifics, but it was something like:
" You're blessed +1 scroll of scare monster glows silver for a moment" after reading a scroll of enchant armor. I remember that it was an impossible message (as there is no +1 scroll)

I have encountered similar things like that. You throw a tripe ration and the log talks of throwing your armor etc. Since the right thing seems to happen and not what is shown in the log I've been blaming it on the core so far :)
