Bug#921559: MTP broken for number of phones with "LIBMTP PANIC: Unable to initialize device"

[Dominique Dumont]

Hi

I had a similar issue.

Turns out that Gnome's gvfs was locking the mtp device.

Since I run KDE, I've removed gvfs-backends package and rebooted.

I now can run mtp-detect without issue.
