Yes.

You need to set your breakpoints AFTER the modules are loaded.

1. Disable preloading. (gdb doesn't get along with preloading)
2. Break after library load.
gdb command "break TRACE_init" should do the trick for gbx.
(TRACE_init() isn't called until after LIBRARY_load_all() in gbx.c, as 
far as I can tell.)
3. Set your breakpoints.
4. "c"ontinue execution.
