The related nginx conf is:  
if ( !-e $request\_filename) {  
rewrite ^(.\*)$ /blog.php?q=$1 last;  
break;  
}

Try

```
location / {
    try_files $uri /blog.php?q=$uri;
}

```

Igor already provided correct method to do what you want, but it  
would be helpfull to debug SIGSEGV as well. Please obtain  
coredump and show backtrace, i.e. output of

gdb /path/to/nginx /path/to/nginx.core  
bt

Also please show output of nginx -V and full config.
