I couldn't get it to crash but I found a very strange thing indeed - it
put the 401 response into the cache which obviously is wrong. Also -
there were some memory leaks where response headers were not freed.

Could I get you try this patch (which here leaves no problems in purify
what so ever)

If it works then I will commit it - sorry about these stupid bugs :(
