Storing the same data twice is almost always going to end in things going wrong.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Separating was required for comparison purposes in statusMessageStack, because round-tripping through onRequestedPresenceChanged, m_lastUserPresence.statusMessage() wasn't consistent enough to use the user-set presence variable for anything useful. Also because with booleans for indicating active plugins it's more straightforward to properly control what is saved as a user presence. This allows to use user presences and status messages reliably in statusMessageStack(), and, also dump a piece of (spotted) redundant code in addition.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I don't understand why we're splitting status messages and statuses.
You're not saving disk writes/anything as the next if statement is going to trigger anyway as the statusMessage in the struct will differ.
You're now actually doubling it. </pre>

Stuffing it into a new presence variable works just as well for saving and leave no changes for autoconnect, but adds 3 lines of code including a new global presence specifically for writing to disk.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">What confuses me is in the original design this bug shouldn't exist. m_lastUserPresence should contain the last *user set presence* which is what we should return to after all plugins terminate.
Clearly if m_lastUserPresence doesn't contain the last user presence something is very wrong. Anything else is either a bodge _OR_ the original design is flawed and we need to move to a new design which includes renaming this variable (and/or variable type to Tp::ConnectionPresenceType)
