The bug stills at the 6.3.0. I've been testing further how it works to get
definite patterns and more concrete data. 

Description:
When inserting an OLE objects inside a document it gets corrupted. If the file
is closed an reopened, the preview stills working, but if you double-click, it
is empty.

Summary:
Affected versions: 6.2.* and 6.3.*, might still on 6.4 alpha.
Tested operating systems: Debian 9.9 (linux 4.9.0),  Windows 10, Debian 10
(linux 4.19.37).
Instalation: offictial msi installer / offitial deb packages.

Data:
- It has already been verified that is not an issue related to corruption in
the user profile.
- The OLE objects witch get corrupted are Impress and Draw modules.
- Whatever is the module in witch is inserted the OLE oject, it gets corrupted.
- A sample document has already been uploaded (attachment 152643).
- The OLE object is lost when it is opened, but only when it was created before
the file was opened (when the OLE object is created everything works fine, if
it is closed and reopened it stills working, the problem begins when the file
is closed and reopened).
- If the document is edited withought opening the OLE object, the data does not
corrupt.
- If the document is opened with an earlier version (6.1.*) the OLE object
works fine, unless if the data has already been lost because the document was
saved after opening the OLE object on 6.2.* or 6.3.*.
- If the OLE object has been created with an older version (6.1.*) it also gets
corrupted.

Reproducing instructions with the sample document:
1. Open the document (with 6.2.0 or later).
2. Open the OLE object.
3. Observate.

Reproducing instructions:
1. Create a blank document.
2. Insert a drawing or a presentation.
3. Insert something in it, for example a rectangle (very visible).
4. Save the document.
5. Close the document.
6. Reopen the document.
7. Open the OLE object.
8. Observate.
