AttributeError: 'NoneType' object has no attribute 'replace'

Binary package hint: revelation

I imported a MyPasswordSafe file, clicked on one of the entries, and got an error dialog with this traceback:

Traceback (most recent call last):
  File "/usr/bin/revelation", line 413, in <lambda>
    self.tree.selection.connect("changed", lambda w: self.entryview.display_entry(self.entrystore.get_entry(self.tree.get_active())))

I think is similar to my bug report at http://svn.codepoet.no/revelation/ticket/285 . Maybe you should add your trace there too.

[Marius Gedminas (mgedmin)]

I'm certain that that's a different bug, but adding mine to the upstream bug tracker seems like a good idea.

I made it work with this patch to
/usr/share/pycentral/revelation/site-packages/revelation/util.py,
but I don't know if it's the right fix.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

[Vaida Bogdan (vaidab)]

I switched to Mac OS X so I can't test this again.

[ghostonline (ghostonline-deactivatedaccount)]

I cannot reproduce the bug and as the original reporter is unable to test the new version of Revelation, I will mark this report as invalid.

I had the same problem (Revelation 0.4.11, Ubuntu 8.04), fixed /usr/share/pyshared/revelation/datahandler/pwsafe.py with this patch:
