An internal error occurred during: "Fetching affected paths".

This is my environment:
    Windows XP SP2
    Eclipse 3.1.0
    latest subclipse version
 
See attached image file. The error was caused from within SVN Repository view, when a right-click command, 'Show in Resources History', was invoked on a individual file.

 
This is from the .log file:
    !ENTRY org.eclipse.core.runtime 4 2 2005-08-17 15:14:35.453
    !MESSAGE An internal error occurred during: "Fetching affected paths".
    !STACK 0
    java.lang.NullPointerException
     at org.tigris.subversion.subclipse.core.history.LogEntry.getLogEntryChangePaths(LogEntry.java:134)
     at org.tigris.subversion.subclipse.ui.history.HistoryView$FetchChangePathJob.run(HistoryView.java:1174)
     at org.eclipse.core.internal.jobs.Worker.run(Worker.java:76)
 
 
 
This is coming from my Console window:
        RA layer request failed
        svn: PROPFIND request failed on '/'
        svn: PROPFIND of '/': 405 Method Not Allowed (http://svn.baucanada.com)

Any ideas about the cause of the problem_
