perhaps the WikiStart page was cached by my proxy server so i got the WikiStart Page so i can delete or rename an non-existent page. maybe it is a false bug.

Milestone: 1.0.2
Release Notes: modified (diff)

Or you had that page still present in another tab or another browser, yes.

The internal error is not so nice, we could at least raise a TracError for this, as this is quite easy to trigger.

Done so in r11795.
