This issue happens on Android KitKat and earlier versions. In group messages, it can also force the recipient to leave the group.

How to solve the problem?

Easy, but you should be quick so that at no time the application will show the error message. You must click on the conversation the message came to, activate the options menu and delete the dialog. Once the chat has been deleted, WhatsApp returns to normal.

As a matter of fact, it's also good to make a backup of your messages on WhatsApp, so you won't miss a thing if someone sends you the infamous message.
