Many enchantments cause "Bad compression" kick

[Mathias]

Whenever I try to apply more than 14 different enchantments to an item, I get kicked for "Bad compression" when opening my inventory while in creative mode. This does not happen when I'm in survival mode.

Why does this happen, and can it be avoided in some way? I've noticed that I get kicked for the same reason when creating items with a lot of data.
