!! I've exactly the same issue, under very similar circumstances. It started 
occurring under standard Debian Sarge, for both 3.0.12 and 3.4.1, mysql 4.0and 
4.1.

Easiest way to reproduce: Toggle "Let this user be granted rights". 
Some other administrative tasks also cause it to hang.

Symptoms: Apache child process is using all cpu, slowly eating all memory.

Associated rt.log entry is:
[Mon Sep 12 18:42:07 2005] [warning]: Deep recursion on subroutine 
"RT::ACE::_Value" at /usr/share/perl5/DBIx/SearchBuilder/Record.pm line 425.
(/usr/share/request-tracker3.4/lib/RT.pm:277)

It also happens with the standalone_httpd. I haven't tried the debugger yet.

The problem does NOT (immediately) occur with a new database. Only the 
imported one.

Any pointers (other than starting over:) are appreciated. I'd be happy to 
collect more data.
Thanks
