I got past the issue and wanted to post my solution here for other SVN
admins/users.  HTH.

> I've got a distant user who cannot reliably view the SVN log messages

>From inspecting the Apache logs, I found that the user's client was in an
invalid state.  Somehow it was sending the server requests for revisions
that did not modify any files in the selected directory.  For example, 
Revision 2688 does not exist on Path/To/Directory, but this was in the 
access_log:

"REPORT /svn/<RepoName>/!svn/bc/2688/Path/To/Directory HTTP/1.1" 404 247

His TSVN client was also displaying revision 2689 in the Show Log windows.
After asking the user to disable log caching and clear his saved data he
was able to view the log messages again without clicking 'refresh' and the
invalid revision 2689 disappeared from his TSVN window.

> Provider encountered an error while streaming a REPORT response.  [500, #0]
> A failure occurred while driving the update report editor  [500, #103]
> Error writing base64 data: Software caused connection abort  [500, #103]

As for these other error messages, I'm still not sure the reason but there's
no pressing need to investigate at the moment.  If I find a solution later
I'll make sure to post it here for everyone.

Best,
Shaun
