subpage link with views with a contextual filter causes a 500 server error.

Hello,

I am not sure if this is Node Subpage spesific issue. However below you can find the scenario;

1) I've created a views page with a contextual filter for node Id (nid) ( I've also tried with node title), the views works fine with the filter.
2) I've created a menulink using Node Subpage, and it shows correct with the regarding content type

What happens is when i click the link it gives a 500 Internal error. I've increased the memory from php.ini but made no sense. When i check the error logs, it says favicon is missing. However when i remove the contextual filter the link works fine. I had the same issue with menu tokens also. when i remove the contextual filter from the views things work fine for both modules. I've cleared the cache and tested on diffferent paltform and browsers but the result is the same.

This is not a production site, i try to test the modules for creating content type based menu solutions, you may check on
