            Bug ID: 121737
           Summary: DATALOSS: Saving a new document can silently overwrite
                    an existing document
           Product: LibreOffice
           Version: 6.0.5.2 release
          Hardware: x86-64 (AMD64)
               URL: https://bugzilla.opensuse.org/show_bug.cgi?id=1117300
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: UI

This is a copy of a bug I reported on openSUSE's bugzilla. OS is openSUSE Leap
42.3.

$ rpm -q libreoffice-calc
libreoffice-calc-6.0.5.2-24.2.x86_64

I have just lost 2 documents because of this bug. First time I had a doubt that
maybe I made a mistake. Now I am sure this is a bug and not a user mistake.

How to reproduce:

$ mkdir ~/Documents/bug
$ cd ~/Documents/bug
$ touch data.ods
$ echo foo > crap.csv

Now start Libreoffice Calc, type "bar" in the cell A1 and save the new
spreadsheet. Navigate to ~/Documents/bug and select "data.ods" in the list
(this is the key step to trigger the bug!) Then edit the input field at the top
to replace ".ods" with ".csv". The input field now reads "data.csv". Press
Enter and, if asked, confirm that you want to save in CSV format. You are
prompted for formatting details of the CSV file, click OK.

Now look at the name of your document in the top bar. It is NOT "data.csv" as
you asked. It is "crap.csv". You can check that file "crap.csv" now contains
"bar":

$ cat crap.csv
bar

The original contents of the document is forever lost. Libreoffice did not even
ask for confirmation before overwriting the existing document.

The bug is not specific to Calc, the same bug can be reproduced with Writer,
using appropriate filename extensions.

Further investigation revealed that this bug only happens with the gtk3 UI.
When using the gtk, kde or generic UI, the bug does not happen.

The bug was also reproduced with versions 6.0.7.3 and 6.1.3.2 on the same
system, downloaded from build.opensuse.org, as well as with version 6.1.2.1 on
openSUSE Tumbleweed (32-bit x86).
