            Bug ID: 474672
           Summary: Compressing multiple files from different directories
                    may produce a corrupted archive
    Classification: Applications
           Product: dolphin
           Version: 23.08.1
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal

SUMMARY
If you switch Dolphin into details view mode, expand one or multiple
sub-directories of your current directory, select multiple files from different
directories and compress them using the right-click menu, then the resulting
archive may be corrupted.

STEPS TO REPRODUCE
1. Create a directory structure as if by the following shell commands:
    mkdir -p ~/bug/foo
    touch ~/bug/foo/bar.txt ~/bug/baz.txt
2. Open ~/bug in Dolphin, switch to details view mode and expand directory foo
3. Select files foo/bar.txt and baz.txt (e.g. by control-clicking). Directory
foo should remain not selected.
4. Right-click one of selected files and select Compress -> Here as
"Archive.zip" (compressing as tar.gz results in the same bug)

OBSERVED RESULT
The created archive is corrupted. If you open it in Dolphin, it shows that the
archive contains only bar.txt. If you open it in Ark, it shows an error message
saying that the archive "contains ill-formed entries and might be a malicious
archive". If you run unzip -l on it, it outputs:

Archive:  foo/Archive.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
        0  2023-09-19 01:21   bar.txt
        0  2023-09-19 01:21   ../baz.txt
---------                     -------
        0                     2 files

EXPECTED RESULT
I would expect the archive to contain bar.txt and baz.txt without any directory
entries. So, in general i would expect Dolphin to place all selected files or
directories into the root of the archive. But, i guess, someone might expect
Dolphin to recreate parent directories of all selected files or directories
inside the archive up to current directory or the closest common parent
directory (i.e. in this case the archive would contain foo/bar.txt and
baz.txt).

SOFTWARE/OS VERSIONS
Linux: KDE neon 5.27 (neon-user-20230914-1959.iso, live session)
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.110.0
Qt Version: 5.15.10

ADDITIONAL INFORMATION
I have just checked what GNOME Files does (in Ubuntu 22.04 live ISO i had
laying around), and it seems to do the first option i have described above.
