pcmanfm-qt requires refresh to determine MIME type of new files

[brudan]

Is anybody out there running OpenBSD 6.4 with LXQt 0.13?

x11/lxqt/pcmanfm-qt does not immediately parse new files to determine their MIME type. I've not been able to fix this, despite investing several hours and also asking for help in the LXQt support forum (the folks there are very friendly and helpful but do not have a lot of experience with our favorite OS).

Easiest way to reproduce the problem is to download or create any file to one's desktop. For example:

1.

$ import -window root ~/Desktop/test.jpg

2. Right-click on the file’s icon on the Desktop, choose Properties. It says “MIME type: text/plain” (wrong).

3. Open up a file manager window, navigate to ~/Desktop, press F5 to refresh.

4. Back at the desktop: Right-click on the file’s icon, choose Properties. Now it is says “MIME type: image/jpeg” (correct).

Does anyone know how to make pcmanfm-qt immediately parse new files to determine their MIME type, on OpenBSD? I suspect I'm either missing a helper package, configuration setting, or environmental variable, but I just don't know enough about Qt or LXQt (or GUIs in general) to figure this out on my own.
