I thought these messages were harmless :/ I also get something like this,
always for all (my) Qt apps:

X Error: BadDevice, invalid or uninitialized input device 155
  Major opcode: 144
  Minor opcode: 3
  Resource id: 0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 155
  Major opcode: 144
  Minor opcode: 3
  Resource id: 0x0
Failed to open device

AFAICR this started somewhere since some Qt 3.3.x, don't know really since...

Again , I think this is simply noise, but can be hidding something under
the sheets .... :)
