Actually, the same happened with me (same issue as wodon's)

I'm running a public server
-No response (sometimes) after name selection.
-Zoning into glookingdeep (No response - restarted server)
-Zone into home town - worked fine. Killed a few rats in oggok.
-Zoning to innothule swamp (No response - restarted server)

So, I will try the "delete from merchantlist_temp" idea
Apart from the huge wait during zoning, game runs flawlessly!
