Thanks for the report, the patch is coming.

[diegognt]

Happen to me, right now

[anjerodesu]

Happened to me today. Very rare moment as this is the first time I encounter such bug. Anyway, what I'm doing is closing tabs, probably fast enough that this error came up.

[abe33]

@diegognt & @anjerodesu If you you have the same Atom version as the initial reporter I urge you to update (Atom has moved past the 1.0.0 milestone now so maintaining old pre-1.0 version is a no go).

If not, can you open a new issue with some details about the context? (the stack of the initial report is irrelevant then).

[anjerodesu]

@abe33 yep, sorry about that. Kinda busy earlier that I forgot to check whether the issue is still open or not.
