Bug#225287: found solution

[Kevin Renskers <chookie@dualdot.com>]

Okay, after even more searching through all the bug reports, I came 
across http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=224049 (in 
section libapache-mod-perl).

And indeed, after disabling mod_perl, apache is working again. When will 
this be fixed? And why wasn't this bug posted in the Apache section?
