Under conditions yet to investigate, the underlying QGpgME job produces an empty result, but no error message. This seems to happen, if the original encryption key(s) is unknown, for example. Currently, the message will therefore be logged as successfully reencrypted.
-> Due to the empty result, we can still detect this happening, although we don't have any info, what exactly failed, then
-> Preliminary fix (indicating that there *was* a failure) in work/tfry/reencrypt_log
-> Also needs fixing in (Q)GpgME
