Some packages use the command 'db_title' in maintainer scripts to set the
title for debconf dialogs to a fixed string. Disadvantage is that this
does not allow the string to be translated.
Because of that the command 'db_settitle' (which takes the title form a
debconf template) is normally to be preferred.
Please add a warning against setting the dialog title to a fixed string
using db_title.
A regular expression for that could be:
db_title[[:space:]]+["']?[^\$]
(One of the quotes may need escaping.)
The explanation could read as follows:
Using db_title to set the title of a debconf dialog does not allow for
it to be translated; consider using db_settitle instead.
See debconf-devel(7) for additional information.
For examples of packages currently getting it "wrong" see:
#560314, #560316, #560318, #560319
There will be false positives as some titles being set this way may not
need translation (example in #560315).
The test will miss cases where titles are set from a variable containing an
untranslated string, but those should be extremely rare.
Cheers,
FJP
