Failed to activate the file-icons package At Cannot delete property '/tmp/file-outside-project-dirs.txt'

I managed to narrow down the issue to a minimum amount of steps to reproduce:

1. Open a file that’s located outside of open project folder(s).
2. Deactivate file-icons package
3. Activate file-icons package

By doing some debugging the culprit seems to be that the serialized data is frozen (by storage.lock() upon deactivating the package), so if/when package is activated within the same window session again the package get activated with the very same frozen data.

Also, locked state is never reset/set to false upon storage.init().

I’ll provide a PR promptly with a proposed solution.

Atom’s error output upon thrown error:

Atom Version: 1.12.7 Electron Version: 1.3.13 System: Mac OS X 10.10.5 Thrown From: file-icons package, v2.0.2

Filed a separate issue, then.

But (as far as I know) I didn’t have it installed previously. I hit it after installing it for the first time, as @kalsan said. After I restarted Atom, everything appears to be fine. The link from the error brought me to this issue.
