shortcut is being deleted when you exit the __init__ function - it needs to be
self.shortcut. accelObject should be a QObject with a parent holding a
pointer to it (there's an error in the kglobalaccel.sip file, but it doesn't
change anything yet) - if you make accelObject persistent (self.accelObject),
then instead of locking up the keyboard, the program will segfault in
KGlobalaccelPrivate::activate() when you press the accel key. That's progress
I guess :(
The ctor for KGlobalAccel in sip/kglobalaccel.sip should look like:
KGlobalAccel (QObject*/Transfer/, const char* = 0);
(the /Transfer/ is missing), but that doesn't fix the problem or even change
the results (you also need to run configure.py and recompile if you make that
change).
I'll have to play with is somemore and see what I can figure out. You might
try a C++ version and see if that works.
