Try to type thison gdb command prompt:

directory /path/to/your/tde/main/repo/dependencies/tqt3/src

This should solve the "tools/qglist.cpp: No such file or directory." error.
For example, on my system it is
directory /home/tde_src/1_git/tde/main/dependencies/tqt3/src

Uhm, after a quick look at the rules file, it looks like debug symbol are not generated for kpilot. Will have to fix
that to have more info.

A first rough guess is that the code may actually be stuck in KPilotDeviceLink.cc:517
	while (!fDone)
	{
		TQThread::sleep(sleepBetweenPoll);
	}
