Package: libinput-pad1 Version: 1.0.0-2 When I was backporting input-pad/1.0.0-2 to squeeze-backports, lintian claims that X: libinput-pad1: shlib-calls-exit usr/lib/libinput-pad.so.1.0.0 Which is a bug and should be fixed upstream, it might cause ABI breakage. Note this does not prevent the backporting work. -- Regards, Aron Xu
