Cannot open database because the directory does not exist

[benbucksch]

• File: backup/mail-backup.db
• Windows
• Happens immediately after first setup, when opening a few mails. Then goes away.

Possible causes:

• await SQLSourceEMail.save(this); in EMail.save()
• Speculation: IMAPFolder.downloadMessages() saves correctly, but IMAPEMail.download() does not
• Speculation: Race between the above 2 functions
