Comment (by lutter):

 Cool .. I now have a reproducer. If you do the following in a git checkout

 {{{
   mkdir tests/root/.ssh
   touch tests/root/.ssh/authorized_keys
   ./src/try cli
 }}}

 you get the desired segfault. Ultimately, this comes down to the fact that
 add_file_info calls tree_find_cr with
 "/augeas/files!//.ssh/authorized_keys" which causes the error flag
 AUG_EMMATCH to be set, which is not kicked back up early enough.

 There's a couple of problems with all this. At a minimum we shouldn't
 segfault, need to think about how to deal with the '!//' issue, too.
