I have a very strange situation where the gpg command will fail to verify whether there is valid PGP data in some files. Decrypting these files works flawlessly. Here is an example:

[root@server autoimport]# gpg -vv --verify-files 01UserEnumswValues.txt.asc.txt gpg: armor: BEGIN PGP MESSAGE gpg: armor header: Version: GnuPG v1.4.7 (MingW32) :pubkey enc packet: version 3, algo 16, keyid F0682D87CF4ED243 data: [1022 bits] data: [1024 bits]

[root@server autoimport]# gpg -vv --verify-files 03users.txt.asc.txt gpg: armor: BEGIN PGP MESSAGE gpg: armor header: Version: GnuPG v1.4.7 (MingW32) :pubkey enc packet: version 3, algo 16, keyid F0682D87CF4ED243 data: [1021 bits] data: [1023 bits] gpg: no valid OpenPGP data found.

Note that the first file is correctly identified as OpenPGP encrypted data, and has exit status of 0.

The second file gives the error "no valid OpenPGP data found", even though I'm able to decrypt the file with no problems. Both these files were encrypted with the same key, and both contain plain text CSV data.

Any ideas why this is failing on some files and not others?
