Comment 11 for bug 1778069

Around Fedora 27, Nautilus stopped being able to open files with double click. It took me a very long time to figure out what was going on, but it turns out it was this bug:

[Fedora bug]:
[Ubuntu bug]:

I had to remove the following entries from ~/.local/share/applications/mimeapps.list , in the "[Added Associations]" section:


According to the Ubuntu bug, the core problem was fixed in this commit:

However, one commenter on the Fedora bug pointed out that "exo-0.6.2-3.fc16 is still taking the mime types from the X-XFCE-MimeType key and adding them to the [Added Associations] section of ~/.local/share/applications/mimeapps.list". This was still happening on a later version of exo (I don't know which version exactly, but maybe 0.10.x, since Nautilus broke for me around Fedora 27).

There are a few things that need to be fixed:

(1) exo needs to stop inserting these entries in mimeapps.list , if it is still inserting them

(2) exo needs to remove these entries from mimeapps.list, if they are found there, so that upgrading exo is enough to fix a broken system.

(3) One commenter on the Fedora bug pointed out that "I only noticed because some part of KDE was complaining about some lists in mimeapps.list not ending with ';' " -- exo needs to add a trailing ';' if it does need to add (corrected) lines to mimeapps.list.
