GPG Decryption fails for files > 1MB

[david.vazquez_landa at ecb.int]

Hello Werner, 

The files sent to us are already encoded using --armor. Funnily enough, only files larger than 1MB fail. Anything smaller can be decrypted without problems. 

Anyway, thanks for the hint.

Best Regards,

David Vázquez
