random IndexErrors while editing text

[slice]

I've triggered this bug multiple times (I'd say over 10 times) over multiple days. I don't know how to trigger it, as it happens randomly while I'm editing text. It puts Six into an unstable state that can only be restored after a full restart.

Traceback (most recent call last):

I've seen these errors too recently, but I can't pinpoint what triggers them. I will catch the errors and reinit Six for now.

Should be fixed in the latest dev build.

This still appears to be happening for me:

On the latest dev build. It seems to fix itself (although only sometimes).

This one happened immediately after starting Sublime Text (from a completely closed state) and trying to use it.

Using latest dev build at time of posting.

And after opening Sublime Text (from a completely closed state) and clicking somewhere in a file, this error happens:

Traceback (most recent call last):
  File "D:/a/1/six-release\commands\events\event_mouse.py", line 42, in on_post_text_command

IndexError: list index out of range

During handling of the above exception, another exception occurred:

Okay, actually, I think this build is just broken. (Although the above errors are still separate bugs.) Nothing seems to be working, getting constant errors in console.

Will open a separate issue.
