Empty account on Mac

[lexansoft]

I found the problem with empty account. On Mac if you open a folder in Finder, it creates a hidden file .DS_Store. For some reason geth misinterprets it as an empty key. See bellow.

I think the problem is somewhere around crypto/key_store_plain.go:122

nduserca312:~ alexn$ ls -a ~/Library/Ethereum/keys/
. .DS_Store
.. ccd5b5c052fee58d1489104e2d18d4416bde3969

nduserca312:~ alexn$ geth account list
Welcome to the FRONTIER
Address: {}
Address: {ccd5b5c052fee58d1489104e2d18d4416bde3969}

nduserca312:~ alexn$ rm ~/Library/Ethereum/keys/.DS_Store

nduserca312:~ alexn$ geth account list
Welcome to the FRONTIER
Address: {ccd5b5c052fee58d1489104e2d18d4416bde3969}

Btw, if looking into internal Ethereum directories, please use a proper tool such as http://man7.org/linux/man-pages/man1/ls.1.html instead of enterprise-grade tools that automatically pollutes viewed directories with the tool's own config files.

@Gustav-Simonsson Finder is as proper as you can get. It just has this bug, you know, since 1999...

There is also an unfortunate bug that is not fixed to this day that result in an excessive creation of .DS_Store file. Those files should only be created if the user actually makes adjustments to the view settings or set a manual location for icons in a folder. That’s unfortunately not what happens and visiting a folder pretty much guarantees that a .DS_Store file will get created
