>Description:
An assertion in fam fails when it should monitor NFS files/dirs.
>How-To-Repeat:
$ fam -d -v
Start kmplayer as a user, who's $HOME is mounted via NFS
(gdb) r -f -v
Starting program: /usr/local/bin/fam -f -v
fam[13539]: log level is LOG_INFO
fam[13539]: Shutting down connection
fam[13539]: built with IMonNone, so /dev/imon won't be opened.
fam[13539]: Couldn't create RPC TCP/IP client: Invalid argument
Assertion failed: (!strncmp(local_path, dir(), local_dir_len)), function hl_map_path, file NFSFileSy
stem.c++, line 222.
Program received signal SIGABRT, Aborted.
