given that, I understand this part

-            if (strcmp(r->filename, ofilename) == 0) {
+            if (ofilename != NULL && strcmp(r->filename, ofilename) == 0) {

but not the rest of the patch.  why would you need/want to set r->filename
in this instance?

that's a common idiom for we mod_perl people :)
