    This still occurs. Trying to follow what happened here:

    1. r70: create a new, empty branch /branches/r095
    2. r71: copy trunk over to /branches/r095/jsyntaxpane and modify some
    3. r72: some more additions and modifications
    4. r73: more changes and modifications, but some files were svn copied, then the source svn removed, including the following entry:
       A /branches/r095/jsyntaxpane/src/main/java/jsyntaxpane/actions/ (from /branches/r095/jsyntaxpane/src/main/java/jsyntaxpane/actions/
       D /branches/r095/jsyntaxpane/src/main/java/jsyntaxpane/actions/

    It's that entry that hg clone svn+ trips over, as the last line of --debug output shows:

      jsyntaxpane/src/main/java/jsyntaxpane/actions/ searching for copy revision for src/main/java/jsyntaxpane/actions/

    This log entry is emitted a few lines above the traceback.

    One thing to note here is that this svn repository does not use a standard trunk/branches layout. Trunk was copied over to /branches/r095/jsyntaxpane, and I suspect this is what is confusing hgsubversion resulting in incorrect manifest metadata when importing.
