This is borderline ridiculous if you ask me.  What we name our files 
(validly) is instead controlled by a program, maybe a handful of Horde 
admins are running, that objects to our personal naming scheme?

I'd rather not be held hostage by the way some unknown group of people 
think that files should be named.

That rule would complain about a picture of my back door, too. Seems 
overly broad and inflexible. I'm not convinced.

Change silver theme image name "shell.png" to avoid Modsecurity big logs with

Generic Attempt to run rootkit

ModSecurity: Access denied with code 503 (phase 2). Pattern match
"/(?:(?:linuxdaybot|suntzu|shell_vup|shell|(?:o|0|p)wn(?:e|3)d|xpl|ssh2?|too20|backdoor|terminatorx-?exp)\\.(?:dat|gif|jpe?g|png|sh|txt|bmp|dat|txt|js|s?html?|tmp|php(?:3|4|5)?|asp)|(?:r57|fx29|c(?:99|100))\\.(?:txt|php))"

WAF Rules: Possible Rootkit attack: Generic Attempt to run rootkit"] 
[data "/shell.png"] [severity "CRITICAL"

For the file .../horde/themes/silver/graphics/shell.png

YES, a perfectly normal file no problem, however names in modsecurity 
give allerts in ModSecurity if installed on an Apache server

A quickfix would be to rename the file from shell.png to e.g. shll.png 
and theme code referring to the name.
