New description:

 {{{
     self.assertRaisesWith(stem.InvalidArguments, "DisableAllSwap, User
 cannot be changed while tor's running", controller.set_options, {'User':
 'atagar', 'DisableAllSwap': '1'})
 }}}
 or
 {{{
   File
 "/home/travis/build/tlyu/tor/stem/test/integ/control/controller.py", line
 793, in test_set_conf_when_immutable
     self.assertRaisesWith(stem.InvalidArguments, "DisableAllSwap cannot be
 changed while tor's running", controller.set_conf, 'DisableAllSwap', '1')
 }}}

 We don't know why, because we don't have the tor logs or backtrace
 (#30234).

Comment:

 DisableAllSwap causes this error by itself:
 {{{
   File
 "/home/travis/build/tlyu/tor/stem/test/integ/control/controller.py", line
 793, in test_set_conf_when_immutable
     self.assertRaisesWith(stem.InvalidArguments, "DisableAllSwap cannot be
 changed while tor's running", controller.set_conf, 'DisableAllSwap', '1')
 }}}
