Description Rich Burridge 2006-08-15 17:01:05 UTC 
Tested with Ubuntu Dapper Drake, Evolution 2.6.1 and latest
Orca from CVS HEAD.

When the focus is on a message header in the message header
summary list in Evolution mail view, Orca throws the following
traceback:

Traceback (most recent call last):

+ Trace 70503

    row = parent.table.getRowAtIndex(obj.index)
AttributeError: 'NoneType' object has no attribute 'getRowAtIndex' 

The problem here is that parent.table is None, because we have a
"table cell" within a "table cell" as the following component
ancestry shows:

Patch to the Evolution script to hopefully detect that we've just deleted a message.

One situation where this patch won't work is if new messages
arrive in the viewed mail folder between the last time we
had focus in the mail message header summary list and just
after pressing the Delete key.

Still, it does improve the situation.
Comment 2 Rich Burridge 2006-08-15 17:37:16 UTC 
Ack! I attached the patch to the wrong bug. Rejecting it
(as there doesn't seem to be a way of deleting it).
