keybinding capplet doesn't prevent using space or enter key

Sorry, I meant "Backslash", not "Backspace".

This affects the spacebar and various other keys too.

Jason reported in a couple other bugs that:

"I am using Ubuntu 6.06 (Gnome 2.14.3). In the keybinding capplet, when I
change the "next track" keybinding (yes, that keybinding specifically)
to "Ctrl+Alt+n" then it allows me to change the key to "n". This breaks
my "n" key."

and

"I am using Ubuntu 6.06 (Gnome 2.14.3). In the keybinding capplet, when I
change the "previous track" keybinding (yes, that keybinding
specifically) to "Ctrl+Alt+LeftArrow", this seems to break my Left Arrow
key throughout Gnome. Similarly, when I bind "Ctrl+Alt+RightArrow" to
"next track" this seems to break my Right Arrow key throughout Gnome."

Thanks for the bug report. This particular bug has already been reported, but feel free to report any other bugs you find.

Thanks for your reply. This bug appears at first glance to be a duplicate of #40747, but it really is not. I have taken the liberty of reopening the bug and removing the duplicate marking, and I hope this is ok with you.

* 40747 is about binding Ctrl+Alt+${SOME_KEY} to Next Track disabling ${SOME_KEY}. Bug 40747 has now been fixed in feisty.

* My own bug report, above, refers to the fact that you can bind actions to keys like Spacebar. My bug, AFAIK, is still unfixed.

I will describe the bug again with more detail.

Bug description:

In the keybindings capplet, it is possible to bind actions to many different keys, but not to simple unshifted letter keys. If you try to make such an illegal binding, it displays an error message saying that you cannot bind actions to plain old letter keys, only to Ctrl-key, Alt-key, or such. But it unfortunately allows you to bind plain punctuation keys (such as Backslash, Spacebar, or Enter) to actions.

Steps to repro:

1. open keybindings capplet
2. next to the "Open a Web Browser" action, click "Unassigned" to assign a key
3. press the spacebar key
4. open your favorite text editor
5. type: "hello world"

Results:

1. You see "helloworld" with no space.
2. Your web browser launches.

Expected Results:

1. You see "hello world".
