Description Nicholas LaPointe 2017-08-28 12:15:23 UTC 
1. Create new image
2. "Image" -> "Convert Image Color Space" to any color space other than the current one
3. Undo
Comment 1 Halla Rempt 2017-11-27 08:12:12 UTC 
Yes, I see this happening as well.
Comment 2 Halla Rempt 2017-11-27 08:12:27 UTC 
There's also this output:

krita.core: WARNING: Calling synchronous fullRefresh under a scheduler lock held
krita.core: We will not assert for now, but please port caller's to strokes

Comment 3 David REVOY 2018-06-27 17:43:51 UTC 
I can reproduce in Krita4.1appimage:
1. Create a new document (the default 1600x1200 sRGB 8bit with two layer, white background and a transparent)
2. Create two colored dots with airbrush on top active layer
3. Image > Convert Image Color Space, with this settings:
   - Model: Greyscale/Alpha
   - Depth: 32bit , then OK.
4. Wait until the colored dot switch to greyscale.
5. Press Ctrl+Z to undo.
(the infinite "Waiting for image operation to complete" appears)
Comment 4 Antti Savolainen 2018-06-27 17:48:15 UTC 
I can't reproduce this but pressing Ctrl+Z after the color space conversion makes Krita forget it has additional channels.

After Davids steps I was able to reproduce this with the latest git(411dc86): https://youtu.be/qocT-kX64yM

In my case:

    1. "CTRL + N" (New document, any type)
    2. (menu >) Image > Convert Image Color Spece...
    3. "CTRL + Z" (Undo)

Actual Results: the waiting box appears and stays open
Expected Results: waiting box closing when done with the color space conversion.
Comment 8 Halla Rempt 2019-05-09 12:27:04 UTC 
I cannot reproduce this anymore. I suspect it was another instance of the lockless hashtable problem.
