Description Michal Luscon (mail bounces back) 2014-08-22 09:11:52 UTC 
It looks like the fix from #9798 was not sufficient and rsync can still crash after improper iconv call. Any suggestions what might have gone wrong in this case?

Version of rsync:
rsync-3.1.0

You'll need to investigate using debug symbols to try to figure out what call is being made that is crashing the iconv library.
