[Pkg-lxde-maintainers] Bug#1001151: pcmanfm: Debian 11.1.0 LXDE does not mount smart phone properly

[beta-tester]

Package: pcmanfm
Version: 1.3.2-1
Severity: normal
X-Debbugs-Cc: alpha-beta-release at gmx.net

Dear Maintainer,

i am not intirely shure where to report this bug:

i have a strange behavior with Debian Live 11.1.0 amd64 LXDE iso, when i try to mount my Android 11 smart phone plugged in via USB.

mounting my android smart phone always fails in this sequence:
1. boot into Debian Live 11.1.0 amd64 LXDE iso,
2. plug in my phone into the USB port,
3. give access to my files on the phone,
4. mounting the phone via the File Manager (pcmanfm?) will always fail with an error like:
"The name:1.48 was not provided by any .service files"
5. i can successfully mount my old mp3-player via USB.
6. but subsequent plug in and mount, my phone sill give always that error above (steps 2,3,4).

BUT, when i change the sequence after a fresh reboot to:
1. boot into Debian Live 11.1.0 amd64 LXDE iso,
2. i can successfully connect and mount my old mp3-player via USB.
3. unmount and unplug my mp3-player
4. plug in my phone into the USB port,
5. give access to my files on the phone,
6. i can sucessfulls mount and access files of my phone.
7. unmount and unplug phone
8. i can also successfully repeat steps 4,5,6,7 without any error.

why can i successfully mount my phone, once my mp3-player was mounted before, but fails when i don't mount my mp3-player first?

when i use the Debian Live 11.1.0. amd64 Cannamon iso, i can always mount my android smart phon successfully - there it doesn't matter what sequence is use, it always succeeds.

why is the mount behavior of Debian Live 11.1.0 amd64 LXDE iso that strange?
PS.: also Raspberry Pi OS Bullseye (from 2021-10-30) shows that strange behavior (it is based on Debian 11 bullseye LXDE)
