Expected: An error message

Actual: CF crashes immediately

Steps to Reproduce:
1) Log on as conjurer, but all classes may work.
2) Visit guildmaster in Evermoon, but any guildmaster may
work.
3) Write "prac <long word>" where word is
about 100 characters long.
4) Crash

Repro rate: 2/2

Additional information:
I'm really sorry for the inconvenience of the two crashes:
14. Jan 2008, about 3AM GMT

The first wasn't intentional, as I copy/pasted the wrong
content to the prac command, the second was to be sure that I
was to blame.

The character used to test the error was: Tivanna
