Backtrace: https://bugzilla.redhat.com/attachment.cgi?id=529776

Originally reported about 3.7.9, reproducable with 3.7.10:

1. put a single message into a local folder, a normal text/plain one will suffice
2. select the message
3. open the mimeview parts viewer with the '<' button right of the message view
4. drag'n'drop a part other than the first one (message/rfc822) to somewhere, e.g. drag the text/plain part into an editor/filemanager
5. Trash/delete the message
6. try drag'n'drop in the _empty_ mimeview parts window area -> crash

There may be other/similar test-cases, which would also lead to mimeview_start_drag running into a NULL ptr.

possible fix

This untested patch may fix the issue, as done in other invocations of mimeview_get_selected_part.
