Description

I mirrored a subdirectory of a master repository, and then svn log -r {yyyy-mm-dd} is no longer working. The returned error breaked my http server with "500 Internal Server Error". It might be a bug.

# svn log -r {2014-06-10} file:///path/hided/repo
svn: E160000: Failed to find time on revision 4794
# svn log -r 4794 file:///path/hided/repo
------------------------------------------------------------------------
r4794 | (no author) | (no date) | 1 line

------------------------------------------------------------------------
# cat /path/hided/repo/db/revprops/4/4794
END

I have found this is being discussed before.
