Zim says "Page object became invalid" when I try to save a copy of the notebook.

[Vanamali]

I typed some notes into Zim desktop wiki and wanted to save it in a directory different of where I opened it. A window with title "Looks like you have found a bug" popped up. It read "AssertionError: BUG: page object became invalid // When reporting this bug please include the information from the text box below" and gave the following details:

Further, this "AssertionError: BUG: page object became invalid" message kept popping up whenever I tried to repeat the above said steps (Irrespective of the contents of the notebook.)

Afraid the debug output is not complete, can you first close all zim
instances ? See the message at the end of the output.

Thanks,

Jaap

Sorry! I overlooked the message. The (possibly) complete output is given below.

Yes, that is full debug output, but it doesn't seem to show the error.
Did you trigger the error while making this debug log ?

Thanks,

Jaap

[Vanamali (vanamalishastry)]

Yes I did. But, haven't witnessed further occurences.

OK, than let's leave the bug at "incomplete" for now, if you see new
occurrences you can change it back to "new".

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:
