[Paparazzi-devel] strange problem when running the GCS programs

[Chris]

Hi.
I get a strange error (the one you see later) which affects the 
telemetry among other things but only the first time i run the GCS 
programs, if i stop/remove all running processes then the next time 
everything runs fine.
I am running Ubuntu 12.04 LTS and the very latest master although i have 
been seeing this error
regularly for the whole past month

Here is the control_panel.xml part

   <program name="GCS_C177" command="sw/ground_segment/cockpit/gcs 
-speech -layout CEF/C177_layout.xml -mplayer 'tv:// -tv 
driver=v4l2:width=640:height=480:norm=PAL:input=1:device=/dev/video0'">
      <arg flag="-b" variable="ivy_bus"/>
    </program>

   <session name="C177 cam joystick @115200">
      <program name="Joystick">
         <arg flag="CEF/Saitek_Aviator_camera.xml"/>
         <arg flag="-ac" constant="@AIRCRAFT"/>
      </program>
      <program name="Data Link">
         <arg flag="-d" constant="/dev/ttyUSB0"/>
         <arg flag ="-transport" constant="pprz"/>
         <arg flag="-s" constant="115200"/>
      </program>
      <program name="Server"/>
      <program name="GCS_C177"/>
   </session>

Here is the output containing the error:

Fatal error: exception Not_found

The same happens to all my aircrafts where i just change the aircraft 
name and probably the baud rate.
