Both libusbhid (system library) and libhidapi (3rd party library) provide a function called hid_init. Dolphin was being linked to both. The WiimoteScannerHidapi constructor was calling hid_init without arguments. libusbhid's hid_init expects one argument (a file path). It was being called as if it was defined without arguments, which resulted in a garbage path being passed in, and because of that, the Qt GUI was failing to launch with the following error: 'dolphin-emu-qt2: @ : No such file or directory'
