No part of a state definition should trigger an additional state change (for that particular stategroup), as the state machine can't handle changing from one state to another until it has completely entered the first state. You might be able to get some useful debug information using the environmental variable STATECHANGE_DEBUG (set to 1) -- it should be able to at least tell you the second state that is being triggered.
