Comment 1 for bug 1774878

Google Translate from German to English indicates initial description is:

"since I used Caliber on Ubuntu 18.04 LTS, the Caliber Editor does not show a table of contents of the index_split_xxx.html files on converted PDF files. If I do the same under Windows 10, the ad is ok.

The fault diagnosis yields this:"

And the last sentence is:
"What can I do that I can - converted PDFs again as usual - edit?
regards
efri"

Thanks
