Cannot list item when space in the value

Just some more information, I use WordPress 3.2.1 and CFT 1.4. I also noted when I try to list a custom field with space in the value the mysql stops responding. I’ve been using 2.9.2 of WordPress and it worked fine. Now the mysql stops responding or crashes which makes my hosting service quite unhappy. I should also say that I got about 12k posts on my site and think that this is related to these articles/bugs

I know that this plugin is not developed anymore, or that it has taken another road. But has anyone else had this problem? Or how to solve it?
