[solved] 4.1 Release - Logs show htaccess rewrite errors

[robfrew]

I updated to the latest 4.1 release today since it was rereleased with some bug fixes. Now, in my log files during start up. I immediately see these errors, repeating about 8 times:

[[HTAccess]] rewrite: '%' must be followed by a digit for a RewriteCond backreference. while parsing: RewriteCond %%{ENV:LS_AI_PATH} ^$

[[HTAccess]] rewrite: invalid rewrite condition while parsing: RewriteCond %%{ENV:LS_AI_PATH} ^$

Since it doesn't tell me where this error originates from, I have know idea how to look for it.
