you know, it takes longer when you don't know what to write ;-)

indeed, if you build shared libraries that "gnokii" executable is a
libtool wrapper, so you need this:
libtool --mode=execute gdb --args ./gnokii --identify

the bug must be in common/devices/dku2libusb.c between lines 289 and 302:
get_iface_string(usb_handle, &DEVINSTANCE(state)->manufacturer,
        current->device->descriptor.iManufacturer);
get_iface_string(usb_handle, &DEVINSTANCE(state)->product,
        current->device->descriptor.iProduct);
get_iface_string(usb_handle, &DEVINSTANCE(state)->serial,
        current->device->descriptor.iSerialNumber);
get_iface_string(usb_handle, &DEVINSTANCE(state)->configuration,
        current->configuration_description);
get_iface_string(usb_handle, &DEVINSTANCE(state)->control_interface,
        current->control_interface_description);
get_iface_string(usb_handle, &DEVINSTANCE(state)->data_interface_idle,
        current->data_interface_idle_description);
get_iface_string(usb_handle, &DEVINSTANCE(state)->data_interface_active,
        current->data_interface_active_description);

that's why it would be very useful to get debug symbols with line
numbers in gdb, else use the old way: add a dprintf() after each of
those lines to see where it fails

what version of libusb are you using?
pkg-config --modversion libusb
