Comment 1 for bug 354172

python-xdg was added for bug 177095, but I verified that the code doesn't fail any more if it isn't installed, so this can go (it will stay on apport-gtk).

gdb needs to stay, I'm afraid, since otherwise you cannot call gdb to create the Stacktrace, Registers, etc. fields, which many hooks, bug report default title, and other things depend on.
