The problem seems to be in the following file at line 273:
/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_basic_tagcloud/package.module.nextgen_basic_tagcloud.php
I removed the following line at 273:
$wp_query->is_page = FALSE;
And now my conditionals are evaluating properly again.
Hope this helps someone else.
