Public bug reported:

Bash completion for Inkscape does not work in Ubuntu 18.04. It will for
example suggest non-svg files.

The reason seems to be that /usr/share/bash-
completion/completions/inkscape uses the have() function, which is
temporarily defined in /usr/share/bash-completion/bash_completion, but
then unset at the end of that file.

Workaround: Copy /usr/share/bash-completion/completions/inkscape to
~/.local/share/bash-completion/completions/inkscape and remove the uses
of "have".

The bash completion for some other commands seem to use have() too, e.g.
jackd, ufw, cowbuilder, dpatch_edit_patch, and axi-cache, so bash
completion for these commands will presumably not work either.
