MTP is very unstable on Plasma 5

Hi there.

Ever since I installed Arch/KDE MTP has been a pain in the butt for me. I'm using Samsung Galaxy S3 running Android 4.3 and Plasma 5 with KIO-MTP.

So most of time when I plug in the phone and try open it with Dolphin I get the message 'The mtp protocol died unexpectedly'. This produces an error stack like this:

 kio_mtp(2962)/kio MTPSlave::MTPSlave: Slave started
kio_mtp(2962)/kio DeviceCache::checkDevice: new device, getting raw devices
Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
kio_mtp(2962)/kio DeviceCache::checkDevice: No Error, continuing
kio_mtp(2962)/kio DeviceCache::checkDevice: Found device matching the Solid description
ignoring libusb_claim_interface() = -6PTP_ERROR_IO: failed to open session, trying again after resetting USB interface
LIBMTP libusb: Attempt to reset device
ignoring libusb_claim_interface() = -6LIBMTP PANIC: failed to open session on second attempt
kioslave: ####### CRASH ###### protocol = mtp pid = 2962 signal = 11

Sometimes it works though, I have no idea why: is it having screen unlocked (I've read that this was the workaround, but this doesn't work all the time), having the battery fully charged/not fully charged or whatever.

Currently if MTP fails I either use Bluetooth/AirDroid for small files or transfer files to SD card directly. However, this is obviously very unhandy.

AFAIK so far this problem hasn't been fully resolved, but hey, the hope lives on, so I ask for help of those who have fixed similar problems before/has more experience in Plasma ecosystem.
