gee_array_list_real_get: assertion failed

[trappedinspacetime]

I get the following bug:

 ERROR:arraylist.c:1181:gee_array_list_real_get: assertion failed: (index >= 0)
 Bail out! ERROR:arraylist.c:1181:gee_array_list_real_get: assertion failed: (index >= 0)
 Aborted (core dumped)

Similar bug reports issued throughout in vala applications. Possible cause explained here

There is a fix in this link but I don't know how to apply it in this case.
