[Catacomb] Problems running catacomb on Apache 2.2.2



Hi,

I am trying to run catacomb-0.9.2 on Apache 2.2.2 ( with mod_dav working  ) , but I get a segfault whenever the server receives a request on '/repos' ( default catacomb config ) . Following is the gdb backtrace:

(gdb) run -X -d ..
Starting program: /usr/local/apache2/bin/httpd -X -d ..
[Thread debugging using libthread_db enabled]
[New Thread -1210677024 (LWP 24368)]
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName

Program received signal SIGSEGV, Segmentation fault.

the 'str' pointer is NULL, because 'r->filename' and 'r->path_info' are not set, strangely , both filename and path_info are available in dav_get_resource but are set to NULL when passed to dav_repos_get_resource. Maybe this has something to do with apr memory management ( which might have changed from apache 2.0 to 2.2 ). Does anybody have an idea why this might happen ??
