Bug#610499: mozilla-devscripts expands ${xpi:Depends} too narrowly

[Daniel Kahn Gillmor]

Package: mozilla-devscripts
Version: 0.25
Severity: normal

I help maintain xul-ext-monkeysphere for debian and as part of
upstream.

Upstream mainly uses debian, and we maintain an apt repo for users of
other debian-style systems to pull from.

We just got this report upstream that the xul-ext-monkeysphere package
depends on iceweasel, even though firefox should satisfy the
dependency:

  https://labs.riseup.net/code/issues/2716

The debian packaging uses ${xpi:Depends} in debian/control (and
therefore depends on mozilla-devscripts to expand the value).  it
seems like this should be iceweasel | firefox since those applications
share a uuid, right?  however, it appears to only expand to iceweasel,
which makes the upstream-generated package fail on ubuntu.

If i'm misunderstanding what mozilla-devscripts is supposed to do,
feel free to clarify and close this bug.

Thanks for maintaining mozilla-devscripts!
