Comment 7 for bug 1066455

This bug is appearing on one of my Zim notebooks.

I had renamed one of the parent page something like this:

Ideas --> 10_Ideas

This page had many children. A few days later I noticed that apart from the "10_Ideas" page, the old "Ideas" page was also present. All the children of this "Ideas" page were also visible but greyed out. There was no content however on this page. I checked my the folder where this notebook was. There was no such page as "Ideas" in this folder. I tried updating the index but nada.

Then, I tried deleting this ghost page "Ideas" and this is the error it showed:
