Subject: bash-completion files of grub and git prevent xsession to start with gdm3

Date: Mon, 17 Oct 2011 22:21:50 +0200

[Message part 1 (text/plain, inline)]

Package: bash-completion
Version: 1:1.3-1
Severity: important

Dear Maintainer,

due to *possible* errors within /etc/bash_completion.d/git and /etc/bash_completion.d/grub, gdm3
cannot start the xsession.

After purging bash_completion logon works find.

The issue is could be within:
 - bash_completion, which maybe is not that fail safe on script execution
 - git and grub, because the scripts have errors
 - gdm3, because it isn't that fail safe as well
 - *any other suspect*

 
I have no idea what the root cause is, please try to find a solution.

Thanks alot,

Thomas

Those files are not provided by us. Next time, please report your bugs to the
correct packages ;)

Thanks for reporting it.  The bash completion script uses bash syntax,
but it seems that in your configuration a different shell is trying to
parse it.  Could you send your shell initialization files (~/.xsession,
~/.profile, ~/.bashrc, and so on)?  Actually, it might be simplest to
try

	grep bash_completion ~/.* /etc/*

Sorry for the trouble,
Jonathan

Hi Thomas,

Thanks for the quick response.

This part looks sane.

[...]

> /etc/profile:    . /etc/bash_completion

This looks broken.  You can see the default /etc/profile in
/usr/share/base-files/profile.  It relies on bash.bashrc to source the
bash completion scripts, doing so only when the "$BASH" envvar is nonempty
(so it does not get run by other shells).

It would be possible for /etc/bash_completion to give a more specific
error message when it is being run by something other than bash, but
that would have the downside of hindering development of bash-style
completion scripts meant to be run by other shells that handle most of
bash's features (like zsh).

Hence closing.  Where did those lines in /etc/profile come from?

Hope that helps,
Jonathan
