This is actually triggered by the completion code called with
COMP_CWORD=0, meaning prev=${COMP_WORDS[COMP_CWORD-1]} will trigger an
error.

BTW, this is not mandriva, nor urpmi specific: the issue can easily get
reproduced with any other completion, such as ssh, for instance:

[guillaume at oberkampf bash-completion (master)]$
(reverse-i-search)`ssh ': ssh -a oberkampf
<TAB>
[guillaume at oberkampf bash-completion (master)]$ bash: COMP_WORDS: bad
array subscript

I just modified  _get_pword to avoid this potential error. Completion in
history search context is still quite useless, but at least it doesn't
output error.
