System Ubuntu 10.04 with all current updates.
Evolution 2.28.3
I forced closed the PDF attachment print job. Shortly after I was unable to receive email. I CAN send emails, but CANNOT receive emails.  Each time when send/receive is requested the "Error while fetching email". Clicking on the error message shows "File is encrypted or is not a database". I set up another laptop with the same versions (did not try to restore or move the old information) and it sends and receives correctly.
How do I correct this issue?

Ran CAMEL_DEBUG=all evolution >& evo.log and received the following messages in the top 25% of the log.
