K4dirstat installer registers incorrect inode/directory MIME type

[Kalle Tuulos]

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Ubuntu 20.04.4 LTS

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
k4dirstat:
  Installed: 3.2.0-1build1
  Candidate: 3.2.0-1build1
  Version table:
 *** 3.2.0-1build1 500
        500 http://fi.archive.ubuntu.com/ubuntu focal/universe amd64 Packages
        100 /var/lib/dpkg/status

3) What you expected to happen
4) What happened instead
When K4Dirstat is installed, it adds following row to /etc/mailcap:
inode/directory; k4dirstat --icon k4dirstat -qwindowtitle "K4DirStat" "%s"; test=test -n "$DISPLAY"

This is problematic, as this causes K4Dirstat to be default MIME handler for directories.
Practical example of this problem is, when some script uses "xdg-open" to open directory, it then opens K4Dirstat instead of system's normal file manager.

In my computer, I corrected this by commenting out the line.

Correction: don't add the MIME registration to /etc/mailcap -file.

No. k4dirstat just add /usr/share/applications/k4dirstat.desktop. An other package (maybe mailcap or mime-support) hook the installation process to regenerate /etc/mailcap.

/etc/mailcap is a generated file so you'll have to redo this change every time you install a package.

There is no way to specify a MIME priority in a .desktop file. Users are expected to configure this priority them self. To do so edit/create $HOME/.config/mimeapps.list (user specific) or /etc/xdg/mimeapps.list (system wide) and add:

[Default Applications]
inode/directory=thunar.desktop

xfce4-mime-settings provide a GUI for that. I guess that KDE and Gnome have similar tools.

[Kalle Tuulos (kalle.satel.tuulos)]

The root problem is, that the /usr/share/applications/k4dirstat.desktop file has following line:

  MimeType=inode/directory;

This line should be removed in order to avoid this problem.
