@ilew go ahead and fix it in extras.

One request:
very often i see the error "impossible to download" when i receive messages with one image but without any text inside. (or corrupted text part? - no idea)
Then, looking in the fmms folder, i can find the new folder with the image correctly saved.

In case of an error during the download, would it be possible to manage the problem evaluating the presence of new files (not empty) asking confirmation before open them?
(Example: an error has occurred during the download but one part of the message has been saved. Do you want to open it?)
