Of course :
* ejabberd version is 2.1.8 (it's a home hosted server, it used to
work until a few weeks ago)
* swift revision is commit 5dc7d1459b966ba5b848760bc43cbb1242d5da80

Here are the values :

(gdb) print recent
$1 = {static npos = 18446744073709551615,
  _M_dataplus = {<std::allocator<char>> =
{<__gnu_cxx::new_allocator<char>> = {<No data fields>}, <No data
fields>}, _M_p = 0x7fffffffb7f0 "\001����\177"}}

(gdb) print chat.jid
$2 = {valid_ = true, node_ = {static npos = 18446744073709551615,
    _M_dataplus = {<std::allocator<char>> =
{<__gnu_cxx::new_allocator<char>> = {<No data fields>}, <No data
fields>}, _M_p = 0x809919558 "dtc"}}, domain_ = {
    static npos = 18446744073709551615,
    _M_dataplus = {<std::allocator<char>> =
{<__gnu_cxx::new_allocator<char>> = {<No data fields>}, <No data
fields>},
      _M_p = 0x80994fb68 "conference.alkumuna.eu"}}, hasResource_ = false,
  resource_ = {static npos = 18446744073709551615,
    _M_dataplus = {<std::allocator<char>> =
{<__gnu_cxx::new_allocator<char>> = {<No data fields>}, <No data
fields>}, _M_p = 0x8024226b8 ""}}}

For some reason, I cannot access activity[0] in gdb, here is activity
however that seems to be empty if I'm not mistaken (so it would
explain my activity[0] problem)?
(gdb) print activity
$1 = {<std::_Vector_base<std::basic_string<char,
std::char_traits<char>, std::allocator<char>
>,std::allocator<std::basic_string<char, std::char_traits<char>,
std::allocator<char> > > >> = {
    _M_impl = {<std::allocator<std::basic_string<char,
std::char_traits<char>, std::allocator<char> > >> =
{<__gnu_cxx::new_allocator<std::basic_string<char,
std::char_traits<char>, std::allocator<char> > >> = {<No data
fields>}, <No data fields>}, _M_start = 0x0, _M_finish = 0x0,
      _M_end_of_storage = 0x0}}, <No data fields>}

(gdb) print chat.isMUC
$2 = true

(gdb) print chat.nick
$3 = {static npos = 18446744073709551615,
  _M_dataplus = {<std::allocator<char>> =
{<__gnu_cxx::new_allocator<char>> = {<No data fields>}, <No data
fields>}, _M_p = 0x809916388 "Matthieu"}}

Thanks for spending time on this,
