Comment # 1 on bug 8283 from 
I checked in a fix for the gui part in r47399.

However, I was wondering how we end up in that situation. It seems that dumpcap
initially reports that the wlan0 interface supports monitor mode - and later it
turns out that this is wrong.

pcap_can_set_rfmon() and pcap_set_rfmon() both return success

The error shows up in pcap_active(), which returns PCAP_ERROR_RFMON_NOTSUP
Therefore, get_if_capabilities() returns NULL.

Should we handle the PCAP_ERROR_RFMON_NOTSUP case explicitly and retry without
setting monitor mode?
