Browser gets None from fs.revision_prop(LOG)

[bkc@…]

It looks like Browser.py fails because this line (about line 89 in Browser.py) returns None

change = svn.fs.revision_prop(self.fs_ptr, created_rev,
   svn.util.SVN_PROP_REVISION_LOG,
   self.pool)

I'm running subversion 1.1.2 on RHEL3 (and a damn nightmare it was getting python bindings to work)

Anyway, 'change' is None in some cases, generating this traceback:

Traceback (most recent call last):

    real_cgi_start()

    info = self.get_info(path, rev, rev_specified)

    item = {
  File "/usr/local/lib/python2.3/site-packages/trac/util.py", line 62, in wiki_escape_newline
    return text.replace(os.linesep, '[[BR]]' + os.linesep)
AttributeError: 'NoneType' object has no attribute 'replace'

My temporary fix is this:

 change = svn.fs.revision_prop(self.fs_ptr, created_rev,
    svn.util.SVN_PROP_REVISION_LOG,
    self.pool) or ''

#1092 and #1093 were actually duplicates (same reporter, similar issue, this one in the Browser, the other one in the Log view)
