Sure; if you have the 'strace' program, you could use that to figure out
what NM is doing.  When you run NM, open a new terminal and do:

strace -p `pidof NetworkManager`

Then mail the output for a duration of about 10 seconds or so in a
reply.

Second, if you have 'gdb', you should try this:

gdb attach `pidof NetworkManager`

Then, when you get the (gdb) prompt, type:

t a a bt

(That's "thread apply all backtrace") and mail the full output of that
as well in a reply.
