As I said, then you need some outside computer you can ssh to.

Could you please try this:

  sudo apt-get install devscripts
  apt-get source libgphoto2
  cd libgphoto2-*
  DEB_BUILD_OPTIONS=nostrip,noopt debuild -us -uc

This should build a debugging version of libgphoto2 and produce some
.debs. Install them with

  sudo dpkg -i ../*.deb

Then please try

  gdb --args /usr/lib/libgphoto2/print-camera-list hal-fdi

Type "run", let it crash, then do "bt full", and copy&paste it here.
If the first few lines are still "??", we need to look further where
this happens, and install more debug symbols.

Thank you, your help is much appreciated!
