Lua error when trying to use items from the bag (equip anything, quest item etc)

[Pocokk]

Which software were you running?

• Addon version name: 11.0.2
• Client used: Cataclysm Classic

Have you read the changelog?
Yes I did

Please describe the bug.
Lately when I try to use any item from the bag, occasionally the game blocks the addon and I have to /reload in order to make it function again.

Please describe how to reproduce it.

1. Play the game for a period of time (can be 5 minutes, can be 10, join into a dungeon, leave etc)
2. Open your bag
3. When you click on a usable item (potion, flask, halloween mask, quest item), you'll get an addon blocked error message.

Any Screenshots?
