Undefined variable: args in _shortcode_filter_tips()

Hi there. I installed the D7 version of the module to see if it was usable for my site but immediately when I tried accessing the Filter Formats and when I tried to create a new content I got these warnings, and no tips for the available shortcodes appeared (as per screenshot):

Notice: Undefined variable: args in _shortcode_filter_tips() (line 76 of /var/www/site/sites/all/modules/contrib/shortcode/shortcode.module).
Warning: call_user_func_array() expects parameter 2 to be array, null given in _shortcode_filter_tips() (line 76 of /var/www/site/sites/all/modules/contrib/shortcode/shortcode.module).

I dived into the code and found the function and the line reported in the warnings and $args is indeed not being defined anywhere. Changing '$args' to 'array($format, $long)' seems to solve the issue and the tips start appearing on the wysiwyg when creating content. As I might need this module for a D7 project I 'll continue testing and report my findings here.

Thanks a lot for your time and the module.
