[rt-users] 3.0.7 upgrade problems

[Kevin Murphy]

Hi,

I upgraded to 3.0.7rc1, and now users can't take tickets (they experience a 
system error, described below).  I upgraded to 3.0.7, and the same error 
occurs.  I am using PostgreSQL 7.3.4, Apache 1.3.28, mod_perl 1.28, Mac OS X 
10.2.8, with all RT dependencies up to date (e.g. DBIx::SearchBuilder 0.94).
Additional note: I followed the directions in the UPGRADING document, with the 
exception that I added a semi-colon to the third postscript-specific line.

P.S.  Here's the error which occurs when a user steals/takes a ticket:

System error
