bash-completion is a separate package, and reports should go here:
http://bash-completion.alioth.debian.org/

It seems to get stuck here:

[...]
+ return 1
+ return 0
+ local ext regex tar untar
+ [[ 4 -eq 1 ]]
+ local 'tars=@(@(tar|gem|spkg)?(.@(Z|[bgx]z|bz2|lz?(ma)))|t@([abglx]z|b?(z)2))'
+ case ${words[1]} in
+ case $prev in
++ sed -e 's/^.* \([^ ]*\) .*$/\1/'
+ tar=a.tar.bz2
+ untar=t
+ local 'IFS=
'
+ COMPREPLY=($( compgen -W "$( printf '%s\n' $( tar $untar $tar                 2>/dev/null ) )" -- "$cur" ))
++++ tar t a.tar.bz2
++ compgen -W '' -- ''
+ return 0

in the tar t a.tar.bz2

I'm CC'ing bash-completion-devel to take the issue there.
