Oddity with filename completion in the minibuffer

Oddity with filename completion in the minibuffer

[Reuben Thomas]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I have a directory structure like this:

~/.sylpheed/
   sylpheed.log
   sylpheed.log.bak

You can see the precise keystrokes I used below, but basically, I typed

~ / . s y l <tab> sylp <tab> . <tab>

and got ~/.sylpheed/sylpheed.log.bak, when I should have got
~/.sylpheed/sylpheed.log. If I type "~/.sylpheed/sylpheed.log" and press
<tab> then I get the message [Complete but not unique] as expected. Emacs
seems to work correctly on similar examples, just not this one.

I tried this running emacs -q to make sure it wasn't a result of my
configuration.

See the variable completion-ignored-extensions.  ".log" is one of them.
