Arch Linux

In LXDE pcmanfm doesn't close on shutdown/reboot. There is also a bugreport in Red Hat Bugzilla. Since my English is bad and I'm lazy, I copy the text from there:

https://bugzilla.redhat.com/show_bug.cgi?id=1797193

Description of problem:

Whenever I request a shutdown or reboot, I get this:
Waiting for stop job for 1 min and 30 secs.

Version-Release number of selected component (if applicable):

pcmanfm-1.3.1-2.D20181227git0619a81f.fc31.2.x86_64

How reproducible:

Always (at least on my system which is running as a qemu/kvm guest).

Steps to Reproduce:
1. Reboot and log in to lxde.
2. Request a shutdown.
3. wait for the reboot to complete

Actual results:

Shutdown takes a long time.

Expected results:

Shutdown would be just as fast as in the previous fedora version.

If I interpret this correctly, the remaining process would be pcmanfm.

I would be nice if I could attach strace to that process, but strace itself would be terminated too early to be useful.

There is already a patch:

https://src.fedoraproject.org/rpms/pcmanfm/blob/4b1c3e3004e996ea3192f1725d3b8a916c7c3ab5/f/pcmanfm-0201-main-set-the-GIOChannel-encoding-to-binary.patch

So I suggest to include this patch.
