Ok, I've retested this and find that dh_strip outputs the following:

  dh_strip -plibglib2.0-udeb  --dbg-package=
  Option dbg-package requires an argument

But it does not fail.

It seems that failing on an invalid option is a change introduced only in
debhelper compat level 8, whereas this patch only updates glib2.0 to use
compat level 7.

My branch history seems to confirm that this was only needed while I was
experimenting with compat levels >= 8.

I'm pretty sure that I have *used* the glib2.0 dbg package in Ubuntu since
making this change, so for some reason it seems to work despite the bug you
mention above.  But if you think it's safer to retain the --dbg-package=
argument, there doesn't seem to be any harm.

Thanks,
