GPGMail 2.5b6

Cannot decrypt messages from drafts. Saved draft messages appear with no content and I get a "decryption failed with unknown error" bar. When I click on "details" I get the following:

An unknown error occurred while decrypting this message.
GPG error message:
gpg: problem with the agent: No pinentry
gpg: encrypted with 4096-bit RSA key, ID 05B2E47D, created 2015-03-11
"Dimitris Fekas [email blocked]" gpg: public key decryption failed: Operation cancelled
gpg: decryption failed: No secret key

    This started happening to me just now. Same version. I hadn't updated GPGTools. I hadn't restarted

    Hi dimi and James,

    thanks for taking the time to report this problem. It is a known issue and I have connected this discussion with the existing ticket. We have yet to find out, what exactly is causing this, but assume it is related to sleep / wake behavior of the mac. Are you using sleep mode?

    The workaround is, to simply restart your mac and you should be back in working state.

    We'll update this discussion as soon as we have news about this issue.

    If you have not already done so, please do update to the latest GPG Suite 2015.06 stable release (from our website).

    All the best,

    Hi dimi and James,

    good news. We think, this issue has been fixed. If you want to test the fix, please download our latest nightly GPG Suite. That page also has sig and SHA1 to verify the download. It would be very helpful, if you can provide feedback, as to whether the fix works as expected.

    If you have other questions you can open a new discussion any time.

    Best, steve

    Disclaimer: This is a development version which has not been thoroughly tested yet, so bugs or crashes are to be expected. Thanks for helping us test this fix.
