help diagnosing crashes that happen when guake window is open

[jonathanstrong]

Describe the bug

Hello. I am a longtime, avid user of guake, and I am having trouble with persistent system crashes which invariably occur when the guake window is open (toggled on). I am posting this issue as a request for help to diagnose what the underlying problem is.

About once a week, my computer crashes, becoming completely unresponsive. The monitors are frozen in place, mouse and keyboard input does nothing, and the machine will no longer respond to a ping over the network.

The one persistent aspect of these crashes is that I am always working in my guake dropdown terminal at the time.

When I hard reboot the machine, the logs end abruptly, typically very soon after the "Sending 'toggle' message to Guake3" was written.

Guake is a critical part of my workflow and I'm getting a bit desperate to figure this out. I recently built from master and was using that in hopes it might resolve the issue, only to have suffered a crash just now.

Expected behavior

System continues to operate normally.

Actual behavior

System becomes completely unresponsive.

To Reproduce

Frequently use guake on my cursed workstation for about a week.
