That's an easy one :-)

You are modifying the list in the loop until g_list_next() returns
NULL ...

so you are now trying to iterate over an empty list (events == NULL).
You probably want a dedicated variable for the iteration, e.g.
GList *iter;
events = g_list_reverse (events);
for (iter = events; iter; iter = iter->next)
/* do stuff */;
for (iter = events; iter; iter = iter->next)
/* do other stuff */;
