It might be considered a bug in bash-completion, which is a separate
project from bash.

Since you're not on the current stable release of Debian, your best
course of action is probably to determine whether the same problem
still exists on Debian stable (or even unstable/testing), and if so,
to report the bug to Debian.  The Debian bash-completion packager
can decide how to proceed from there.

It's been my experience that Debian bug reports for older-than-stable
releases are not likely to accomplish much.  YMMV.
