the later crash appears to come from some minstrel bugs. i.e.,
MinstrelWifiManager::InitSampleTable initializes the sample table on line 787:
station->m_sampleTable[newIndex][col] = i+1;
Note the '+1' above: it sets an index in the sample table equal to
GetNSupported (station) which leads GetNextSample later to return this invalid
index in the minstrelTable.
Removing the '+1' or adding a (i+1)%GetNSupported(station) makes the code not
crash for me.
I guess that this is something for duy to look at now.
