XF 1.1 Weirdest title issues in XenForo

I have something really weird happening in XenForo: If I create a thread title with specific keywords on it, the title is completely hidden. For example, as soon I create a thread with keyword "CentOS" on it, the entire title disappears in forumdisplay view:

As soon I remove the "CentOS" keyword, title shows back like magic. This happens in forumdisplay only, I can see fine the thread title elsewhere. I tried other keywords, the issue happens specifically on "CentOS" keyword only. I'm going to leave the "CentOS" keyword present into title, so you see live what I mean about the thread title. Running a query, the post displays properly the title into database, so is not something related to badly stored data.

I talked to Mike and he has no idea where the issue could be. This is not a browser cache issue, I get this issue on every single possible or impossible browser. Something is definitely wrong and extremely annoying. I would appreciate your help to solve the puzzle. Thank you.

Thinking the obvious and not sure why it would cause that but did you try reverting thread_list_item by chance(if there's any changes made to it)

Well, I don't have mod_security installed, nor Apache. I have nowhere defined in Nginx a rewrite rule related to the above mentioned keywords so the problem is definitely not related. In fact, I run a minimal install CentOS 6 setup with the strictest number of packages installed on my box.

I left in place the "CentOS" keyword, so any ninja coders can look at page output. I'm curious if anyone finds a solution.

Read that thread.
I know Wireshark helped figure out what the problem was.

Weird that the same words tftp, nmap, wget give problems just like mod_security.

Actually, it is not the keyword position but rather the title string length! Whoa...

"Keyword wget turns title blank" OK
"Keyword wget turns title with CentOS keyword blank" FAIL
"Bug in XenForo: nmap" OK

There are no errors present into logs, that is the first thing I looked for. Obvious when troubleshooting things, no?
However, there is someone passionate to check if I have the /forums-open directory on my server:

Stop repeating "mod_security" and "mod" this or that. :ROFLMAO:

Clearer than this... it cannot be.

I have seen this exact problem caused by client applications like Norton Internet Security. Did you try a different computer?
