Strange that the remote server is null.

Possibly a corrupted brigade. I am a little bit astonished that the stacktrace
isn't longer.
So could you please do the following:

1. Add the contents of .gdbinit from the root directory of the 2.1.10 tar ball
to your .gdbinit
   (see http://httpd.apache.org/dev/debugging.html#gdb)

2. Issue the following commands:

gdb /opt/apache21/bin/httpd /tmp/core.25976
bt
frame 2
dump_brigade b
dump_filters f
