Hi Jason,

:filetypes nil

did the trick! I am running OS X 10.10.5 and 'which wish‘ leads


so i guess it is the version coming with the system. I havn’t installed anything using homebrew.

You are of course totally right regarding *. It failed from time to time but than worked perfect again. I guess that’s a pretty noob error I ran into here.

Thanks for your help!

I played around with the filetypes keyword but could not get it running and could not find anything in the net so far which helped me. I actually do not care about the filetype at all.
