Bug ID: 88970
Summary: NameOwnerChanged handlers shouldn't assume that the
bus is behaving correctly
Product: PulseAudio
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Keywords: love
Severity: normal
Priority: medium
Component: modules

Our policy is that we don't trust any external processes to behave correctly.
This means that PulseAudio shouldn't crash or leak memory if some other process
does something unexpected.
NameOwnerChanged handlers, at least in bluez5-util and backend-ofono, assume
that the bus daemon is behaving correctly, i.e. that the old name passed via
the signal really is the old name. We should remember the owner name ourselves,
and complain loudly if the bus daemon disagrees about the old name.
Validating the old name is important, because if the bus incorrectly claims
that there was no prior owner (the old owner is an empty string), we should
clean up our state that we had for the old owner, but currently we don't.
