Error trying to undo more of the possible actions done

[nohamelin]

With Gaupol 0.92:

• Open a big subtitle file (1 hour or longer).
• Do an expensive action (e.g. change framerates).
• Press quickly Ctrl+Z multiple times to undo the action.

While the application is trying to undo the action done (it takes 1-2 seconds here), the second undo request seems be registered too, triggering the following error:

I can reproduce it. I've seen this before and twice done something that I thought fixed it, but I seem to have only tested small actions that were fast to undo. I'll look into it.

[nohamelin]

Yeah, I remember seeing it occasionally in the times of... uh, Gaupol 0.19, maybe. On the other hand, it is the first time that I see it with more recent releases.

[nohamelin]

I tried the master build with this fix; it's working fine, as far as I could test it.

Good to hear. Thanks for testing.
