Hi to all,

sorry for the "wrong" bug report. I've been playing around with things
and finally came to the conclusion that the error I'm experiencing is
NOT related to wpasupplicant, but due to a bug in madwifi.

sorry^2 for not being able to tell you exactly, where the bug is hidden
nor being able to give you a patch, but at least I can confirm that
using madwifi from svn (I used snapshot madwifi-ng-r1794-20061104) fixed
the reported bug.

If I can be of any help, please let me know!



PS: Have I mentioned that K/Ubuntu rocks (as does Debian)?
