ZimDesktop crashes on inserting an image in a table

Hello,
if a zim-wiki file containing a table is modified in a regular text editor, ZimDesktop 0.65 on Linux crashes on opening the notebook, if the table contains a link to an image. Sample table:

| ColumnOneWithImage<| ColumnTwo |
|:-------------------|:----------|
| {{../santacl.jpg}} | text |

However, a table containing an image is not a problem for Zim parser - it can be exported just fine using command line version:

/opt/zim/zim.py --export \
  --format=html --template=Default \
  --output=/tmp/zim-bug/zim-export-to-html/html --index-page=sitemap \
  /home/user/Test/notebook.zim

 The resulting HTML works fine and displays the image in the table.

I have included in this report a sample Notebook ("Test") with a text file containing a table with an image; I included also the correct html and shell command used to generate it in "zim-export-to-html" folder.
Since the parser works fine from the command line I think it is a problem only for the GUI application, but I am not sure.

Thank you very much for the Zim program, I enjoy using it very much and it useful for me ( I am a teacher).

The crash dump report by ZimDesktop 0.65 on Linux AMD64 when opening that table with an image is:
