SUMMARY: AddressSanitizer: 15384 byte(s) leaked in 377 allocation(s).

The likely culprit is pam_bt_pair.c::process_dbus_bt_list

Tasks/Goals

• Read glib documentation to figure out which function calls allocates memory
• Squash all memory leaks

Summary

To fill out once the issue is to be closed. Give a short summary of the changes you made to implement or fix an issue

[zakuArbor]

g_variant_iter_next requires one to free the key and value pair at each iteration
* reduced 335 bytes
g_variant_dict_init requires a call to clear the dictionary

SUMMARY: AddressSanitizer: 14450 byte(s) leaked in 344 allocation(s).
