[Bash-completion-devel] Bug#668265: Enabling 'set -e' in the shell causes bash-completion to terminate the shell.

[Shalom Bhooshi]

Package: bash-completion
Version:    1:1.99-3


BEHAVIOUR
Enabling 'set -e' in the bash shell (either explicitly or via a script
sourced into the shell) causes bash-completion to terminate the
interactive shell in an unexpected fashion. This is probably because
the auto-completion functions throw an error that is not handled and
the 'set -e' which is inherited from the shell by those functions
causes the shell's process to exit immediately - as opposed to the
functions exiting immediately i.e. a failure in the auto-completion
functions (wrongly) affects parent shell.

REPRODUCTION
Enable `set -e` and then attempt to tab complete for some arbitrary
command that has no tab-complete functionality e.g.
