This is happening because your clipboard is not garbage collecting itself like it's supposed to, and it grows and grows and grows until it becomes unmanageable. I had this happen on 8.4 because I jailbroke it and some mod wasn't releasing clipboard handles correctly so nothing ever got removed from the clipboard*. So resetting all settings (which really means "nuke everything on the data partition that's not an app, not an app's library, not an app's document, not a file, not a photo and not the iPod") should erase the entire clipboard and it should then start working.
* you can't actually access old clipboard contents, but anything that's started pasting it needs to be able to access the thing it's pasting until it declares that it's done, so if it doesn't do that it has to stay on disk forever. This isn't supposed to survive a reboot, but apparently the clipboard can get confused and then it can.
