Subject: cfg80211_mgd_wext_connect() and wpa_supplicant don't like each other

Hi !
When I'm using
* wpa_supplicant
* a static WEP network block
* wext-compat in linux-wl
I always get two errors when roaming (that is, not at the first
connection):
1252921234.926116: CTRL-EVENT-SCAN-RESULTS

I traced this down a bit into wext-sme.c, cfg80211_mgd_wext_siwfreq().
This function run's cfg80211_mgd_wext_connect() and this function
returns -2.
Isn't this a bit fishy? Why should a connect function be called
when user-space wants to changes the frequency? And if for some
reason this is really helpful/necessary, why return the failure
to do so as an error result back to the original "just change the
frequency" call?
In the end, this here:
1252921276.268451: Association request to the driver failed
1252921276.355482: Associated with 00:1b:53:11:dc:40
looks quite contradicting :-/
