Trivial Description
$ svnadmin create /tmp/repo $ svn co file:///tmp/repo -d wc $ svn mkdir wc/foo A wc/foo $ svn ci wc Adding wc/foo Commit succeeded. $ svn up -r0 wc Segmentation fault The problem is that revision 0 doesn't have an author property. When send_entry_props in libsvn_ra_local/update_editor.c calls svn_repos_get_commited_info it gets a null pointer for last_author. This gets passed to svn_stringbuf_create_from_string which tries to reference last_author->data and dumps core.
