As Francois said - you have provided way too little information.
 
The GPSMapedit code is completely irrelevant.
(a) It is a couple of years old - it is quite different to the code of the current version.
(b) It is not complete code. I haven't checked to see if it has the gdb-reading code. Did you?
 
And more importantly - the issue is not with GDB, or GPSBabel. It is with YOUR FILES.
 
People (including me) use GPSBabel all the time with GDB files. It just works.
 
You should provide a test file that doesn't work, and ideally find, or edit it down to, the smallest test case that generates the error.

GpsMapEdit is loading such GDBs without problems and here is the source:
http://www.geopainting.com/en/src.html
Maybe you guys can find some useful informations in there.
