[PyQt] Undefined "typeinfo" for KDEDModule while trying to create PtKF5

[Shaheed Haque]

Phil,

That was the problem:

$ python
...
>>> from PyQt5 import QtCore
>>> from PyQt5 import QtDBus
>>> from PyKF5 import KDBusAddons
>>> help(KDBusAddons)
...etc...
>>>

As you suggested, I did some debugging, and the code seems to get right to
the bottom of sipKDBusAddonscmodule.cpp, such that some printf-debug like
this :

    outfile << "at line " << __LINE__ << "\n" <<
    " QtCore: " << sipModuleAPI_KDBusAddons_QtCore <<
    " QtDbus: " << sipModuleAPI_KDBusAddons_QtDBus <<
        " sipModule: " << sipModule << "\n";
    SIP_MODULE_RETURN(sipModule);
}

emits *some* values:

 QtCore: 0x7f0027642c20 QtDbus: 0x7f0027197540 sipModule: 0x7f00307c6e88

even in the error case. Is there some way to make the user experience more
robust in this regard? (I'm going to poke around the PyImport_xxx APIs, but
I assume there is a reason behind what is done at present?).

Thanks, Shaheed
