NullPointerException when viewing history of Page with image - filesystem attachment storage

To reproduce the error do the following:

1. add a new page, edit and save (version 1.1)
2. edit the page, save (version 2.1)
3. view page history, version 1.1 and 2.1 work fine.
4. edit the page, insert an image (version 3.1), save (version 4.1)
5. edit again, save (version 5.1)
6. view page history. Versions 1.1 and 2.1 (before image insertion) work fine, versions 3.1 and 4.1 do not render. Error code follows below.
7. check the filesystem storage: /Page/~this has one folder attachments/
8. now do a rollback to version 2.1 (version before image insertion, new page version is now 6.1)
9. check the filesystem storage: /Page/~this/ has now two folders, attachments/ and deleted-attachments/
10. view page history. Now you can view all previous versions, however the image is not displayed even in versions after image insertion.
11. do a rollback to version 5.1 (new version number is now 7.1). You see the image is now being displayed again and became a new version number image.jpg 1.2
12. view page history. Same experience like in step 10, only the last version 7.1 properly displays the inserted image.

Filestorage settings are:
xwiki.store.attachment.hint=file
xwiki.store.attachment.versioning.hint=file
xwiki.store.attachment.recyclebin.hint=file
