Fatal error with Easysocial/K2 plugin

Hi,

Using K2 2.6.8 and the Stackideas plugin for K2 1.0.5 and Easysocial 1.2.7 (plugin attached below).

There seems to be a conflict with mod_k2_content if the above plugin is enabled:

Fatal error: Call to a member function load() on a non-object in /home/DOMAIN/public_html/plugins/k2/easysocial/easysocial.php on line 443

Two more minor notices:

Warning: Creating default object from empty value in /home/DOMAIN/public_html/plugins/k2/easysocial/easysocial.php on line 248
Notice: Trying to get property of non-object in /home/DOMAIN/public_html/plugins/k2/easysocial/easysocial.php on line 451

When commenting line 443 out, fatal error is resolved:

//$category->load( $article->catid );

A K2 Item page seems to load fine with the plugin even without that modification.

Any suggestions here?
