screenshot showing spurious characters
Description of problem:
Spurious characters are displayed at the top of the keyboard type dialog when booted from the net installer image on a USB stick.
They are "^H^B". Screenshot attached.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Install net installer image on USB stick.
$ sudo livecd-iso-to-disk --reset-mbr --format Fedora-13-Beta-x86_64-netinst.iso /dev/sdc1
2. Boot from USB stick.
3. Press enter until the keyboard type menu is displayed.
Spurious characters, "^H^B", are displayed.
Spurious characters are not displayed.
Yeah this has been there basically forever on ppc64. You're just seeing it now because of the switch to kernel modesetting that puts this code in front of everyone. Any clever ideas are welcome. No one here knows where it's coming from.

You gave me the idea to try some experiments:
1. In basic graphics mode they do not appear.
2. Switching between languages changes what characters are displayed, although the right-most character is always in the same position. Sometimes more than four characters are displayed.
3. Transitioning from the language menu (in English) to the keyboard menu results in a subtle change in the layout of the text (seems to be slightly different spacing).
I didn't realize that the welcome string is translated ...
This looks like a possible problem.
/* clear out top line */
buf = alloca(80);
for (i=0; i < 80; i++)
buf[i] = ' ';
/* buf is not NULL-terminated at this point. */
newtDrawRootText(0, 0, buf);

C program to reproduce this bug
When I run this test program in a gnome-terminal window, I get a spurious '-' character at the end of the line. Putting a null character at the end of buf eliminates the spurious character.
$ gcc newt-test-1.c -lnewt
That is a very good catch!
This should be fixed in the next anaconda release.

I can't see any reason this is marked as an F13Blocker, it's an entirely cosmetic bug. Is there a reason?

I see this bug in F13 TC1, but as I stated it seems to be entirely cosmetic, and I'm having trouble considering it serious / blatant enough to be a blocker. James, Jesse, opinions?

I'm not aware of a release that hasn't had these spurious characters. I'd love to squash them once and for all, but this doesn't seem enough to warrant blocking the release in my opinion.
There is no evidence that this bug causes a problem beyond random characters being displayed.
However, the final release is supposed to be "polished":
"Provide a polished final release suitable for meeting the needs of our Target Audience"
From a software engineering POV, this bug is caused by invalid data being passed to a library. That entails a risk of its own.
the polish requirement is open to interpretation, but the specific criteria for now don't interpret it in a way that would cover this case. I think we can demote this from being a blocker...
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '13'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 13's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 13 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
