The `info line` in particular was given by Ell and will make trace
handling a lot easier as it means we may not have to ask for traces with
debug symbols or gdb with Flatpak. We can indeed get these infos back
ourselves since we are guaranted to use the exact same binaries.

This together with the change in verbose version output I did 2 weeks
ago (commit bc5f6371), allowing us to check the exact Flatpak hash
commit used by a reporter, Flatpak debugging should be a lot easier with
just the simpler stack trace format.
