Can not reproduce using a CCD converted from an Aaruf created by a newer version of Aaru. Converting the Aaruf to CCD using release versions of 5.1 and 5.2 also doesn't seem to cause any issue in extraction, so the issue is/was likely due to Aaru creating an incorrect dump in 5.2. Will close when confirmed.

Was able to recover the exact image used when creating this bug report, and can confirm the Aaruf itself seems to be bad in a way that causes a CCD conversion to produce an invalid image. Converting with the newest version of Aaru still breaks, but converting an image created with a newer version of Aaru works fine. So it has to be that the Aaruf created by 5.2 is subtly incorrect, because extraction from the original Aaruf still works.
