Workaround for Aptimize bug and list access denied in SharePoint

Update: It looks like this was a false positive. Yes, all the errors could be replicated by switching the Aptimize on and off but I could not reproduce this issue in a brand new environment which means, Aptimize might not be the problem here but other environmental issues.
As soon as I have more news/fix/info about it I will update this post. Thanks to all the Aptimize people for the contact and great support on this case.

If you are using a product called Aptimize for SharePoint you might have noticed that it is a great product when it comes to minimizing the footprint in the front end and reducing the rendered size of the output. Unfortunately with great power comes also some inconvenient bugs. Like the one below.
In our test scenario we will have a normal SharePoint document library...
...with versioning, content approval and major and minor versions enabled.
...Nothing unusual here. Very well.
Then we will have a custom SharePoint page with a custom webpart in it that does a simple thing: loop through the specified library and builds up a list of those items who are published or have a published version.
1 private static void LoadFake(SPSite site, string virtualLibraryPath, IDictionary<string, bool> fake)
2 {
3 using (SPWeb web = site.OpenWeb(virtualLibraryPath))
4 {
5 SPList list = web.GetList(virtualLibraryPath);
6 SPListItemCollection items = list.Items;
7 foreach (SPListItem item in items)
8 {
9 if(item.HasPublishedVersion)
10 {
11 // do anything here...
12 }
13 }
14 }
15 }
The code above works EXCEPT if you have at least one item in that library in pending approval state AND you have APTIMIZE installed in the server; then you will see that SharePoint error.
error: access denied - current user - you are currently signed in as: xxx - sign in as a different user
If you go to the event viewer you will notice that Aptimize might be running with no problems at all.

But then a lit bit later you will see these two entries in the event log

The following information is part of the event: A request was made for a URL, http://xx.xx.xx.xx, which has not been configured in Alternate Access Mappings. Some links may point to the Alternate Access URL for the default zone, http://www.www.ww. Review the Alternate Access mappings for this Web application at http://myserver:9100/_admin/AlternateUrlCollections.aspx and consider adding as a Public Alternate Access URL if it will be used frequently. Help on this error:
If you now go to the Aptimize console and turn off the website optimization, the error goes away.
The curious thing. if you debug that code above you will noticed that an exception will happen at line #9.
Apparently Aptimize is doing something under the hood that causes a privilege exception when calling SPListItem.HasPublishedVersion even if you are running as System Administrator and even if you are running using RunWithElevatedPrivileges method. Inspect the returned error and it will see an UnauthorizedAccessException.
The fix for now is to avoid calling HasPublishedVersion until we hear back from the Aptimize guys.
If someone out there seen the same issue and would like to share any ideas, feel free. Meanwhile I hope this workaround helps someone.
See you later
