Broken MTP with latest gvfs-mtp (1.58)

Hi,
After the upgrade to gvfs 1.58 (and its gvfs-* companions), I noticed that I could not transfer files from/to my phone anymore.
I'm using Xfce and usually I do that through Thunar. When the phone is connected it appears in the "Devices" panel.
I need to click on it, accept the connection on my phone and then click again to browse the files.

With gvfs-mtp 1.58, the item appears in the panel, I click on it, accept the request on the phone and... nothing. The item does not reappear in the list.

I tried mtpfs but no luck either.

$ mtpfs mnt/

Downgrading to gvfs 1.57.2 and the problem instantly vanishes, I can browse my phone as usual.

Did I miss something or could there be a bug somewhere with 1.58?

I don't have the mtpfs package installed. Should be independent of the gvfs update tho.

You're right. Which makes this issue even more mysterious.

In the meantime I could reproduce it on another laptop running an up-to-date Arch too.

Can you reproduce it with another *phone*?
gvfs-mtp and mptfs both use https://archlinux.org/packages/extra/x86_64/libmtp/ (not updated in a year) - since mtpfs suggests a problem w/ the PTP layer, do you have more luck w/ https://aur.archlinux.org/packages/simple-mtpfs ?

Also make sure to physically reconnect the phone between attempts, failing w/ gvfs might easily screw up subsequent attempts w/ mtpfs

Sure. I was testing with a Galaxy A51 (Android 13).

When testing with my old Galaxy J5 (Android 5, which is a lot simplier since you don't have to accept the connection every time):
- it's immediately browseable with the machine running gvfs 1.57
- it does not appear on the machine running gvfs 1.58, I just get a

kernel: usb 1-2: new high-speed USB device number 12 using xhci_hcd
