Hi Jouni,

I am seeing the following with latest wpa_supplicant and an up-to-date
Fedora 12.



process 15355: arguments to dbus_message_new_signal() were incorrect, assertion "path != NULL" failed in file dbus-message.c line 1162.
This is normally a bug in some application using the D-Bus library.
  D-Bus not built with -rdynamic so unable to print a backtrace
