Description:
------------
The SVN module http://pecl.php.net/package/svn  calls svn_utf_cstring_to_utf8 to 
convert string to utf-8 encoding without checking the return value of 
svn_utf_cstring_to_utf8.  
When svn_utf_cstring_to_utf8 failed, the *dist pointer will be NULL. Thus the 
following call to svn_path_canonicalize would lead to a segfault.

Test script:
---------------
Call functions like svn_fs_is_file with a GBK encoding filename will cause segfault.
