Sometimes fails to properly decrypt large GPG encrypted messages
When opening e-mails that contain an attachment and that are encrypted and signed with pgp, then often the signature check fails with the message “Error verifying signature: Cannot verify message signature: Incorrect message format”. If this happens, the message is still displayed, however, it is only displayed in raw, i.e., the base64 encoded message is shown including the also encoded attachment.
Sometimes the e-mail has to be reopened several times until the signature check passes once. Reopening it again might again lead to the problem described above. This problem also occurs in the mail preview in the main window and when replying to such e-mails. (In the latter case the raw base64 encoded message is cited.)
Remark: I was not able to reproduce this behavior without an attachment, even not with an e-mail as large as my test attachment (1MB random data). Also, only signing without encrypting seems to not trigger the problem.
