Issue 1:
On Mac, lost a couple files this way. All of which are ymls they are also all in my gitignore. I opened with open with choice and they came back, one by one manually.

Atom version 0.135.0

Mac OS X 10.9.5

Issue 2:
Atom v. 205.0 on Linux

Every package up-to-date.

When trying to fix mismatching tags Atom gets crazy if linter-xmllint is enabled (issue 13 on their repo, where you can find a gist with sample code and reproduce steps): duplication of characters, non-working backspace and starting/closing tags, ecc. A forced close is often needed.

It doesn’t happen always, something like 7 times every 10: I tried finding a logical pattern, but I couldn’t find any, it seems completely random. The linter code seems clean and is really similar to linter-tidy, that doesn’t have this issue.

Here some of the errors (sometimes popups blame atom, sometimes bracket-matcher, sometimes git-diff, sometimes autocomplete-plus; neve linter-xmllint itself), I had to manually copy them as "report issue" didn’t do anything:

This is likely a bug in Atom.

The error was thrown from the bracket-matcher package.
