Description Simon McVittie 2013-09-30 14:32:50 UTC 
>>> import dbus
>>> dbus.lowlevel.Message.guess_signature((42,))
dbus.Signature('(i)')
>>> dbus.lowlevel.Message.guess_signature(dbus.Struct((42,), signature='u'))
dbus.Signature('(i)')

The second one should clearly be dbus.Signature('(u)').

Workaround: use a tuple containing fully-qualified dbus types:

>>> dbus.lowlevel.Message.guess_signature((dbus.UInt32(42),))
dbus.Signature('(u)')

Arrays work fine either way:

>>> dbus.lowlevel.Message.guess_signature([42])
dbus.Signature('ai')
>>> dbus.lowlevel.Message.guess_signature(dbus.Array([42], signature='u'))
dbus.Signature('au')
>>> dbus.lowlevel.Message.guess_signature([dbus.UInt32(42)])
dbus.Signature('au')
