Crash when closing tab with shortcut on ubuntu 19.04

Hi there,

I have been using guake for years without problems, but I recently upgraded to Ubuntu 19.04 and got problem with the shortcut to close a tab. My current version is guake 3.4.0-1.

Why using the shortcut (default one), the tab does not close and it sends an ubuntu internal bug report with these details:

`ProcVersionSignature: Ubuntu 5.0.0-13.14-generic 5.0.6

`

Closing a tab by right-clicking and clicking on "close" works flawlessly.
I tried to compile from source, the tab still does not close but I don't receive the crash report from Ubuntu anymore.
