Whatever ps command you're using here isn't showing the parent process
ID. You'll need the parent PID to know which program isn't cleaning
up its defunct children (zombies).
The "-f" (SysV-ish) option to Linux's ps command will show it:
unicorn:~$ ps -fp $$
UID PID PPID C STIME TTY TIME CMD
greg 999 981 0 Mar26 pts/3 00:00:00 bash
You appear to be using the "f" (BSD-ish) option which shows processes
in a tree-like structure, but I can't tell from your pasted excerpt
whether wpa_supplicant is actually the parent of the zombie, due to
the lack of the PPID field.
If it turns out that wpa_supplicant is the parent, then that's the
responsible party, and that's where you should send your bug reports.
