This may be a security problem, because also the currently running connection is also not shown/named. It looks like wifi is inactive, but the computer may be connected to an insecure, unencrypted or fishy network without user knowledge.

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
