[Kde-pim] Item::setPayload() and Studio 12

Howdy PIMsters,

I'm trying to get the latest PIM snapshot -- that's 4.5.68svn1174542 -- to 
build with Sun Studio 12.1 (not Solaris Studio 12.2). Sudio doesn't always 
agree with g++ over templates. See, for instance

	http://bugs.kde.org/251638

The problem is in Akonadi's Item::setPayload(). In the referenced bug report, 
the solution was pretty simple: do the cast from KCalCore::Event to 
KCalCore::Incidence by hand, and the problem went away. Thanks to Sergio on 
IRC for doing that.

In PIM-proper, though, similar problems reappear:

I have akonadi 1.4.52 installed. This is the *only* instance of setPayload in 
KDE PIM that fails with this compiler. If I turn on verbose template expansion 
in the compile, I get the following (annoying feature of Sun Studio: in some 
template expansions, it never tells you the source line number that 
*triggered* the template expansion. You see that here: line 58 is the template 
definition, but no indication which instantiation it actually is.)

On line 94 of calendaradaptor.cpp, there's an explicit constructor of type 
KCalCore::Incidence::Ptr applied to the Event::Ptr; that one compiles with no 
complaint. Line 148 has a KCalCore::Todo::Ptr, and that fails to compile with 
the errors above. If I add the same explicit constructor for Incidence::Ptr, 
it compiles.

The template-fu going on in Akonadi::Item is too strong for me, which is why 
I'm turning to the list. For the time being, we (the Solaris folks) will be 
munging everything to a KCalCore::Incidence::Ptr and hoping for the best.
