I've just seen this exact problem on a SharePoint 2013 farm as well this morning, but have managed to fix the blank "Composed Looks" list issue, although am still working on the "Change the look" wizard pages.
Edit: found a fix for this too now. See my next post below.
It appears that the process of saving a site as a template and then creating a new site from that template causes the original XsltListViewWebPart used to display the default view of the "Composed Looks" list, to be replaced with a ListViewWebPart,
which appears to be broken.
Edit: have also seen this behaviour on sites created from the built-in templates but haven't determined exactly whether this is a bug. ULS logs never show any errors when this occurs so it appears to be "by-design". Ugh.
There may be a tidier way to fix this, but for now, I used SharePoint Designer 2013 to copy an XsltListViewWebPart from a working "Composed Looks" list, AllItems.aspx page and replaced the ListViewWebPart in the broken Composed Looks
list, AllItems.aspx page with it. There is also some additional post copy-paste tidy up to do on the pasted-in XsltListViewWebPart HTML to get it to work within the context of the site it is now in as it will contain GUIDs and URLs that are only relevant
within the site that you copied it from and these need to be replaced with the GUIDs/URLs from the replaced ListViewWebPart - paste it in a notepad session before deleting/overwriting it so you can grab those bits.
I'll write a more detailed step-by-step if anyone wants it, but this doesn't seem to fix the broken "Change the Look" wizard still, only the "Composed Looks" list default view. I'll look into that now and post back more complete
solution if I can find a fix.
Edit: Found a fix. see my next post below.
Edit Edit: One more thing - on some Composed Looks lists we are seeing empty lists once the default view webPart is fixed up. To correct this, you can copy selected Composed Looks from a working site with a full set.
Before you do that, edit the default view in both the source and destination Composed Looks lists and include the Title field as it is a required field.
Then, you can use Datasheet View (just click the edit list link to put it in Datasheet View mode) to bulk copy/paste Composed Looks between the source and destination lists.
Do a little post-paste tidy up on the URLs as above to make sure that they are correct for their new location and then click on over to your Change the Look wizard.
You should see all of your Composed Looks displayed nicely on the page.
Note that the Current Look might not represent the sites actual appearance as it's settings will reflect the source sites appearance, but you can tweak it with the Wizard now.
