[al3xandru]

Description

Emacs becomes unresponsive when attempting to save the Default layout set up in a project folder with 3 windows and 3 buffers.

Reproduction guide

1. Start Emacs
2. New frame (make-frame-command)
3. Open file (helm-find-files in a .git project)
4. Create 3 windows (sequence: spc w v, spc w l, spc w s)
5. Open files from project in the 3 windows
6. Save layouts by name (spc l S)
7. Select Default

Observed behaviour:

After step 6, a new prompt is displayed and Emacs becomes unresponsive. Force quitting is the only way to get out.

Backtrace

BACKTRACE IF RELEVANT

1. Doing the same sequence with a new layout leads to the same result.
2. All packages are up to date.

[StreakyCobra]

Have you tried selecting [>done<] in the prompt once the layout you wanted to save has been selected the first time?

[al3xandru]

That's the point, attempting to select [>done<], where Emacs becomes unresponsive.

[StreakyCobra]

Ok weird, I can't reproduce on develop right now, it works as expected.

This should be already fixed. Closing issue. let me know if it's relevant for you.
