Sung already mentioned that you might not have the coda module, but...
This may also be the memory corruption problem. The username and
password arguments are being freed, and then the bad pointers are
still being used.
If you comment out the call to dav_mopt_destroy() in davfsd and
rebuild, this might fix it.
