Attachment corrupt after move

I reported this some time ago, but it is still a problem in the latest version emclient-v9.1.2082

If an incoming mail with an attachment goes to the Spam box:

  • If I open the attachment while the message is in the spam box the attachment opens OK

  • After opening the attachment, if I then move it to the Inbox (or any other folder, including the desktop) - the attachment is corrupt and won’t open

  • If I do not open the attachment when the message is in the spam box, it can be moved to another folder and the attachment opens OK.

I have sent the good and bad emails sources to
