New description:

 After a condition is met, MSN commands aren't processed. The connected
 account goes into a zombie mode and doesn't get disconnected unless either
 the server or the client expects some reaction from Pidgin.

Comment:

 My bad. The debug sure was useful though. It seems that not only is the
 challenge not answered, but Pidgin simply doesn't get certain commands
 after a certain condition is met.

 As in the log, after a conversation was established, QNG responses aren't
 received for the PNGs. I tried talking to this zombie account from
 another, and it doesn't process the commands even though I see via
 Wireshark packets being sent to the program.

 As for the challenges, the NS doesn't normally send challenges unless
 pidgin doesn't ping within a few minutes. I'm simulating some msnp
 conversation here just for kicks.
