I have Lubuntu Next 18.04

I do not know if the Lubuntu team modifies the file associations to match the release,
or if the file associations are an LXQt default and are left intact until the user
installs the Distro and modifies them.
I don't even know if the associations are modified if one installs (or removes) an application package.
Therefore, I don't know if this is the right place to report this or not.

At some point after I installed Lubuntu Next, and some favorite applications to supplement or replace those in the default install, I noticed some strange file associations...

A .pdf file currently is associated with LibreOffice Draw (which is unable to open it, and reports "This PDF file is encrypted and can't be opened. ")
I would have expected an association with qpdfview (which opens the file just fine, as expected).

Although I have since apparently fixed it, .jpg files were associated with Firefox.
Since Firefox was not originally installed, I might guess that the association was with a generic browser, which originally pointed to Falkon, but which the installation of Firefox then switched to that browser.
In any event, I might have expected an association with LXImage, as that is LXQt's image viewer.

[There also was some weird association with e-book-viewer(or -editor), but I negligently managed not to write that down. It either was .txt or .odt]
