GUI C-g quit issue

[lyterk]

So, when I'm in the GUI emacsclient, C-g does not work. I've been using the ivy-hydra C-o o command.

System: Ubuntu 16.04, emacs 25.1.2
Symptoms: I'm in an ivy buffer and hit C-g. 'Quit' appears at the top of that buffer, but then it flashes back to the ivy buffer.
Things I've tried: recompiling packages, uninstalling and reinstalling packages, uninstalling and reinstalling emacs, helm (It actually has the same problem)
Things that aren't the problem: I don't have toggle-debug-on-quit enabled
Weird things: If I hold down C-g enough, like for about 5 seconds, it does successfully quit.

Try to bisect your config. I'm pretty sure you can't reproduce the issue with emacs -Q, i.e. without any config. So it means the bug is caused by something there.
Comment out half of your config, restart, check the bug etc.

FWIW I bumped into this too. In my case, something had set debug-on-quit to t. I may have just run M-x toggle-debug-on-quit by accident. It's easily fixed: just run M-x toggle-debug-on-quit again.

@Wilfred debug-on-quit could be the cause. But then the behavior in the OP is exactly what is expected.

[Wilfred]

Yep, agreed. I found this issue when googling my error, and I thought the comment would be useful for future searchers / future me / lyterk.

I also came here for C-g not quitting the ivy-hydra selection. I do not get an elisp error just

An amaranth hydra can only exit through a blue head

M-o and then C-g works. However, I would expect to cancel the entire minibuffer action using C-g, also from the hydra.

@lyterk I assume the problem was debug-on-quit.
@floli Thanks, fixed.
