enters is freed at the end of the funtion (local var).
Use something like

  data_gtk_1 *enters = g_malloc(sizeof(data_gtk_1));

Don't forget to free enters memory, when it's not used anymore:
(before your program quits)

  g_free(enters);

An other way would be to declare enters global...

query_gtk points to unknown memory
