Pasting into Guake terminal starts the Android emulator! How do I stop this?

(Using Ubuntu 17.10) I don't know how this happened. I use Guake terminal and zsh with oh-my-zsh, and also have had the Android emulator(along with the sdk etc.) installed for a long time. For some reason, one day, pasting into Guake using Ctrl-V, the mouse and context menu, or Ctrl-Shift-V, all started to **a)** Open the Android emulator and then **b)** Spit some emulator related garble onto the terminal, followed finally by the text I wanted to paste. I can then close the emulator and use the pasted text. This, as you can imagine, became infuriating. So I just now deleted the entire folder of Android related stuff, the sdk, the ndk's, all tools etc. including the emulator. Now when I paste to Guake I see the line: bracketed-paste-magic:12: no such file or directory: /home/user/Android/Sdk/tools/emulator Followed by: All I know about bracketed-paste-magic is that it is a part of zsh... I have never intentionally used this feature. Any suggestions as to how to fix this?
