Can't delete only remaining version of a Wiki page

[Christian Boos]

Delete page would have worked, but this time I wanted to see what would happen with Delete version 1 when there's only version 1, and …

Traceback (most recent call last):
  File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 335, in dispatch_request
    dispatcher.dispatch(req)
  File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 220, in dispatch
    resp = chosen_handler.process_request(req)
  File "/usr/lib/python2.3/site-packages/trac/wiki/web_ui.py", line 122, in process_request
    self._render_confirm(req, db, page)
  File "/usr/lib/python2.3/site-packages/trac/wiki/web_ui.py", line 252, in _render_confirm
    old_version = int(req.args.get('old_version', 0)) or version
ValueError: invalid literal for int(): 

Curiosity satisfied ;)

Actually the normal "Delete Version" works fine. This occurs only when you go into the "Page History" and select version "1" in both columns to diff, then click "Delete Version 1".

I've got a simple patch, so I'll go ahead and grab this.

Actually you'd get the same problem clicking "Delete" going through the "Last Change" link. Fixed in r3701.
