Hi Jesse, Konstantin,

same problem here, but slightly different.

Setup: 2 Webservers, 1 DB Server. I thought both webservers are configured
the same way. RT 3.6.5 with Apache 2, FastCGI and MySQL 5.0.41.

www1 is displaying everything correct, www2 has the same problems as
described by Konstantin, but not on every Ticket, only from Time to Time.

Got today a error Report on this from my Users with two differents tickets
in different Queues.

Both Servers have Text::Quoted 2.02. This takes me to a point to compare all
perl modules of both servers. This point me to a small difference between
both servers. The working one was the first server we setup, the second one
came some months later. The working server has modules installed which are
mostly many version older than the new one.

Only the Text::Quoted Module i installed after i found a threat from Ruslan.
So i think, not only the Text::Quoted Module alone can be the source of the

Here is the difference between the servers:

I will check now the Apache Error Log for some segfaults.
