[Alpine-info] crash in alpine on closed connection

[Eduardo Chappa]

Hello,

   I do not know exactly what happened that triggered the stream to a local 
folder in unix format to be closed. I know I opened it twice from two 
different places, but that is not the point. The point is that the stream 
was closed, while the folder was open, but the screen that was being 
displayed at the time that the stream was closed was the Main Screen, not 
the Index Screen.

   When I came back to that Alpine session, and saw the Main Screen, with 
the folder closed, I pressed "i" to go to the index, and Alpine crashed. 
The reason is very simple. Alpine called "fetch_firsttext", and on it
it called

     sset = (SEARCHSET **) mail_parameters(idata->stream,
                                           GET_FETCHLOOKAHEAD,
                                           (void *) idata->stream);

which needs to access stream->local, which is NULL, because the stream was 
aborted, so *sset is not accessible, although this processor is happy to 
return a pointer to sset.

Anyway, that should be a simple thing to fix. Thank you for your 
consideration.
