[TkK] Serious Bug?

Hi,

There seems to be a fairly major bug in the Tk implmentation of
Kangband which crashes the game when you try to use a recall scroll in
the dungeon. I've no idea whether this extends to any form of recall
or whether it also applies to recall from quest levels. I've noticed
it playing on two different systems, so I'm pretty sure it's not me.

Anyone else come across this and does anyone have a fix? It seems a
pretty major bug to have slipped past testing!
Cheers,
Matt
