This happens with all PDFs, even small PDF files. The buffer that is shown is not updated to reflect the error status. What's worse is that the error message that is given is absolutely unhelpful. It's unclear what "trace" or "BPT trap" means in this concept, or what the abbreviation "BPT" is supposed to mean. This does not help me as a user in addressing the error condition. I suspect that it needs some ominous conversion tool that is not installed or not installed in the right version. I also looked up the doc string to "doc-view-mode", but it doesn't say anything about pre-requisites. I finally found something in the source code, but looking that up is not obvious and too much to ask of a user (who is not a dev). Also, even with the given information, I can't tell which of the conversion tools it tried to call with what arguments, i.e. which one failed. This needs a much better error message and ideally a bit more documentation. --Apple-Mail-26--301626850 Content-Disposition: attachment; filename=smime.p7s Content-Type: application/pkcs7-signature; name=smime.p7s Content-Transfer-Encoding: base64 MIAGCSqGSIb3DQEHAqCAMIACAQExCzAJBgUrDgMCGgUAMIAGCSqGSIb3DQEHAQAAoIIFxDCCAn0w ggHmoAMCAQICED6shx13jEDrq0eL8FRq5ykwDQYJKoZIhvcNAQEFBQAwYjELMAkGA1UEBhMCWkEx JTAjBgNVBAoTHFRoYXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4xLDAqBgNVBAMTI1RoYXd0ZSBQ ZXJzb25hbCBGcmVlbWFpbCBJc3N1aW5nIENBMB4XDTA4MTIwOTAyMDgwMVoXDTA5MTIwOTAyMDgw MVowYjEQMA4GA1UEBBMHUmVpdHRlcjEOMAwGA1UEKhMFRGF2aWQxFjAUBgNVBAMTDURhdmlkIFJl aXR0ZXIxJjAkBgkqhkiG9w0BCQEWF2RhdmlkLnJlaXR0ZXJAZ21haWwuY29tMIGfMA0GCSqGSIb3 DQEBAQUAA4GNADCBiQKBgQDOdo6kAwlkBxUb8dj4saMbYg4SVng8CUePFn3cjjWrakBTbUVa4Z0n wlUxr7AitEeKhBy5nGhu96+jKUPrCwYNRCZ0l2ovvuGq4z1m1nZ5/c8WvFlVhieuxXMUfmb/O7D3 IojoX6iS8n5MNNU2IWNNT/AD3vOl6DKgOtOw4J9y+QIDAQABozQwMjAiBgNVHREEGzAZgRdkYXZp ZC5yZWl0dGVyQGdtYWlsLmNvbTAMBgNVHRMBAf8EAjAAMA0GCSqGSIb3DQEBBQUAA4GBAIjI8yEW wkiEfA9PMgpjnD6KyCXT0iZjHhW2PkR53yZZLUoTboHnKgsFwYp/gzzIL8J5cvZaRUyMUzXDufPP dRmxxCs2jXXLDD/8bvdvOuMzqgYoFA73fAfsC8S6qUL1PayZ90J8CZHNhDwqWqOA56T+DdKUegJT sqoHKh6OnypTMIIDPzCCAqigAwIBAgIBDTANBgkqhkiG9w0BAQUFADCB0TELMAkGA1UEBhMCWkEx FTATBgNVBAgTDFdlc3Rlcm4gQ2FwZTESMBAGA1UEBxMJQ2FwZSBUb3duMRowGAYDVQQKExFUaGF3 dGUgQ29uc3VsdGluZzEoMCYGA1UECxMfQ2VydGlmaWNhdGlvbiBTZXJ2aWNlcyBEaXZpc2lvbjEk MCIGA1UEAxMbVGhhd3RlIFBlcnNvbmFsIEZyZWVtYWlsIENBMSswKQYJKoZIhvcNAQkBFhxwZXJz b25hbC1mcmVlbWFpbEB0aGF3dGUuY29tMB4XDTAzMDcxNzAwMDAwMFoXDTEzMDcxNjIzNTk1OVow YjELMAkGA1UEBhMCWkExJTAjBgNVBAoTHFRoYXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4xLDAq BgNVBAMTI1RoYXd0ZSBQZXJzb25hbCBGcmVlbWFpbCBJc3N1aW5nIENBMIGfMA0GCSqGSIb3DQEB AQUAA4GNADCBiQKBgQDEpjxVc1X7TrnKmVoeaMB1BHCd3+n/ox7svc31W/Iadr1/DDph8r9RzgHU 5VAKMNcCY1osiRVwjt3J8CuFWqo/cVbLrzwLB+fxH5E2JCoTzyvV84J3PQO+K/67GD4Hv0CAAmTX p6a7n2XRxSpUhQ9IBH+nttE8YQRAHmQZcmC3+wIDAQABo4GUMIGRMBIGA1UdEwEB/wQIMAYBAf8C AQAwQwYDVR0fBDwwOjA4oDagNIYyaHR0cDovL2NybC50aGF3dGUuY29tL1RoYXd0ZVBlcnNvbmFs RnJlZW1haWxDQS5jcmwwCwYDVR0PBAQDAgEGMCkGA1UdEQQiMCCkHjAcMRowGAYDVQQDExFQcml2 YXRlTGFiZWwyLTEzODANBgkqhkiG9w0BAQUFAAOBgQBIjNFQg+oLLswNo2asZw9/r6y+whehQ5aU nX9MIbj4Nh+qLZ82L8D0HFAgk3A8/a3hYWLD2ToZfoSxmRsAxRoLgnSeJVCUYsfbJ3FXJY3dqZw5 jowgT2Vfldr394fWxghOrvbqNOUQGls1TXfjViF4gtwhGTXeJLHTHUb/XV9lTzGCAo8wggKLAgEB MHYwYjELMAkGA1UEBhMCWkExJTAjBgNVBAoTHFRoYXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4x LDAqBgNVBAMTI1RoYXd0ZSBQZXJzb25hbCBGcmVlbWFpbCBJc3N1aW5nIENBAhA+rIcdd4xA66tH i/BUaucpMAkGBSsOAwIaBQCgggFvMBgGCSqGSIb3DQEJAzELBgkqhkiG9w0BBwEwHAYJKoZIhvcN AQkFMQ8XDTA5MDcyNjA2MDgzM1owIwYJKoZIhvcNAQkEMRYEFF3dSZeChs1cj8WUVsY6Rpm8Za3N MIGFBgkrBgEEAYI3EAQxeDB2MGIxCzAJBgNVBAYTAlpBMSUwIwYDVQQKExxUaGF3dGUgQ29uc3Vs dGluZyAoUHR5KSBMdGQuMSwwKgYDVQQDEyNUaGF3dGUgUGVyc29uYWwgRnJlZW1haWwgSXNzdWlu ZyBDQQIQPqyHHXeMQOurR4vwVGrnKTCBhwYLKoZIhvcNAQkQAgsxeKB2MGIxCzAJBgNVBAYTAlpB MSUwIwYDVQQKExxUaGF3dGUgQ29uc3VsdGluZyAoUHR5KSBMdGQuMSwwKgYDVQQDEyNUaGF3dGUg UGVyc29uYWwgRnJlZW1haWwgSXNzdWluZyBDQQIQPqyHHXeMQOurR4vwVGrnKTANBgkqhkiG9w0B AQEFAASBgLiNLJ9HjidHS4cfj1eTcZ6je4grAfYVPXjoGAFC4nG7TT8D0sufjGwJo2JnvfWJ2ml3 zVfumsug8KOTH05y3Cx8Cqfna3HddBP8VF1iOTbOap/U4rr1EnJzwYGdPxeLGP7dlO7yv+gmYrNM oyLLf5okwRPX64GiN89ElEr4Nd2RAAAAAAAA --Apple-Mail-26--301626850--
