I've tried to find a solution, but I didn't quite succeed. You'll have to do
with a workaround. Paul suggested one workaround, although I wonder if it's
really a workaround for your problem. It looks like a way to select the
correct Activity::callback() when there are several overloaded ones. I
mentioned another workaround in comment 4 in that bug report. In your case
it would be
foo(sigc::slot<void, Glib::ustring*>(sigc::mem_fun(*this,
&Activity::callback)));
which is almost identical to what you've used yourself.

Thank you Kjell,
I'm now using your cast solution. Adding a typedef and using a C++
static_cast my test case looks like:
typedef sigc::slot<void, Glib::ustring *> ActivitySlot;
foo(static_cast<ActivitySlot>(sigc::mem_fun(*this, &Activity::callback)));
