[rt-users] Unchecking "Let this user be granted rights" results in hang

[Carl Makin]

Afternoon All,
For quite a while we have been having a problem where is you uncheck the 
"Let this user be granted rights" option the thread goes into a CPU spin 
and never returns.

It happens in all 3.4 (including 3.4.4) and from memory 3.2 as well.

This is an install that started life at 3.0 and has been upgraded 
reasonably frequently.   If I export the database over to a new machine 
it happens there as well.

I just spent most of today upgrading dependancies and working on the 
database trying to make the schema as close to the distribution one as 
possible but aside from the Instance column in the Groups table being 
varchar instead of Integer everything else is either right, or just a 
few extra fields in the table.

I'm stumped.

We have a little under 9,000 tickets so it's not a big database and it 
shows the same behaviour with the production system running FreeBSD 4.9, 
Mysql 4.0.16, Apache 2.0.50, mod_perl 1.99, Perl 5.8.4 and with my dev 
machine running FreeBSD 5.4, Mysql 4.1.9, Apache 2.0.54, mod_fastcgi 
2.4.2, perl 5.8.6.

It looks like someone called "murphy at genome" had the same problem in 
February with 3.2 which is described in this email;

Any help here would be appreciated.


Carl.
