[[!meta title="SIGILL on Mavericks"]]

### Please describe the problem.

gsha256sum crashes continiously, so that excessive logs must be removed and the notebook is not responsive.

Mac OS Mavericks

### What steps will reproduce the problem?

I cannot reproduce it. My guess is that it has problems with special characters in filenames of my music repository.

### What version of git-annex are you using? On what operating system?

Version: 5.20131221-g00d1673
Build flags: Assistant Webapp Pairing Testsuite S3 WebDAV FsEvents XMPP DNS Feeds Quvi TDFA CryptoHash 

### Please provide any additional information below.

I can send you the crash report of hsha256sum if you need it.
