I checked for current version 1.40.0 what the limit is. You can have 6501 different items in your inventory. When you win the 6502th item they display a message telling you that you've reached the maximum. So they at least changed the blank message to something more meaningful.

Yet you can't have one of each CI + the combined collections + talismans, CEs ... so if you have friends with some special gifting abilities or "get soooo many CIs from visiting" (i.e. cheat): don't try to get one of each non-giftable CI, combine the collections. It's the best way to never reach that limit.
