This is an interesting bug, raising at least two bugs:

• the email has an empty part (the text part of a multipart/alternative) and QMF is refusing to load it because the test of properly load is checking if the part is empty.
• Because of this, when opening it, the Nemo plugin is instanciating an empty QMailMessage which is not associated to any account, thus giving it an accountId of 0. This, in turn, makes the email client crash when the EmailMessageListModel key is set to QMailMessageKey::NonMatchingKey().

I've submitted a MR in QMF to solve the first issue (which as a consequence avoid the crash).

The UI is still sensitive to setting accountId to an invalid one. This second issue is still eluding me. I think it's a Qt bug but I cannot find what is triggering it exactly besides setting the key() attribute of the EmailMessageListModel to NonMatchingKey().
