Bug#706564: supertux: joystick input configuration is lost, if supertux is started when the joystick is not plugged in

[Francesco Poli (wintermute)]

Package: supertux
Version: 0.3.3-5
Severity: normal

Hello,
the in-game configuration menu for joystick input lets me assign a different
button or axis movement to each action.
For instance, I may configure the game so that:

  Action       Control
  -----------------------
  up           "Axis -Y"
  down         "Axis +Y"
  left         "Axis -X"
  right        "Axis +X"
  jump         "Button 6"
  action       "Button 7"
  pause/menu   "Button 5"
  peek left    "Button 3"
  peek right   "Button 1"
  peek up      "Button 4"
  peek down    "Button 0"

This is really nice and is automatically saved to ~/.supertux2/config

However, I found that, if you start the game when the joystick is not
plugged in, the program spits out the following messages to stderr
(among many other ones):

  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:234 Invalid button '0' in buttonmap
  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:234 Invalid button '1' in buttonmap
  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:234 Invalid button '3' in buttonmap
  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:234 Invalid button '4' in buttonmap
  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:234 Invalid button '5' in buttonmap
  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:234 Invalid button '6' in buttonmap
  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:234 Invalid button '7' in buttonmap
  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:242 Invalid axis '-2' in axismap
  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:242 Invalid axis '-1' in axismap
  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:242 Invalid axis '1' in axismap
  [INFO] /tmp/buildd/supertux-0.3.3/src/control/joystickkeyboardcontroller.cpp:242 Invalid axis '2' in axismap

and my joystick input configuration gets lost!
In other words, the configuration file ~/.supertux2/config gets
overwritten with default values for joystick input configuration!

As a consequence, next time I start the game with the joystick plugged
in, I have to re-configure the joystick controls from scratch!
This is very annoying!

I am convinced that supertux should remember the joystick input configuration,
even when the joystick is not plugged in.

Please fix this bug and/or forward my bug report upstream.

Thanks for your time!
