I have only just started using Build 65 and have also had the problem.

It appears that the STDERR output from rlog is the cause of the problem and I
have fixed my installation by doing the following:

In the file popen.py:
Change the line:
def popen(cmd, args, mode, capture_err=1):
to read:
def popen(cmd, args, mode, capture_err):

In the file viewcvs.py:
Change all the calls to popen.popen to have an additional parameter set to 1
except for the rlog call which is set to 0.
Change the line:
  rlog =
popen.popen(os.path.normpath(os.path.join(cfg.general.rcs_path,'rlog')), chunk,
to read:
  rlog =
popen.popen(os.path.normpath(os.path.join(cfg.general.rcs_path,'rlog')), chunk,
'rt', 0)

But change:
  fp = popen.popen(os.path.join(cfg.general.rcs_path, 'co'), (rev_flag,
full_name), 'rb')
to read:
  fp = popen.popen(os.path.join(cfg.general.rcs_path, 'co'), (rev_flag,
full_name), 'rb',1)

This then ignores the STDERR stuff from rlog and everything then works. However,
 if rlog returns anything else on STDERR then you wont know about it.

In the end, the code needs to cater for the errors and not just ignore it but
this solution is OK for me.

I committed a test file just fine, except that now ViewCvs won't touch this
If I click a file that I have not yet committed changes to all is well and
the file displays and I can diff it etc. But if I do the same on this newly
committed file ViewCvs throws an error and displays this:

Python Messages:

Traceback (most recent call last):
File "c:\programs\viewcvs\lib/viewcvs.py", line 2710, in main
File "c:\programs\viewcvs\lib/viewcvs.py", line 1774, in view_log

idx = string.rfind(head, '.')
File "C:\Programs\Python22\lib\string.py", line 187, in rfind
return s.rfind(*args)
AttributeError: 'NoneType' object has no attribute 'rfind'

I looked into the RCS file and there was new stuff in each revision
description, three new lines like these:
permissions 666;
commitid 1ec3e2f12c87eee;
kopt kv;

If I remove them ViewCvs starts working again.

Is there anyone with any ideas on why it happened and how to solve this?
Is it only present in the CVSNT Daily Snapshot or is this something
Is there a viewcvs.py fix that covers this problem?
