The manual signal connection functions do not make use of dynamic symbol 
export, so manual connect working and autoconnect failing would indicate 
that there _is_ a signal export problem.  Whether it can be solved or 
not, is another matter.

The code for performing signal autoconnection hasn't changed 
substantially since 0.17, so if things work with 2.0 it is more likely 
due to improvements in glib's gmodule code.

There is no plan to remove the manual connect functions.  If libglade 
could only perform connections based on dynamic symbol lookup, then it 
would be useless to language bindings (and as it happens, I care about 
language bindings :)
