There seems to be a problem with the newer kernels and KDE's 'Solid' backend. There's a bug report here about it.

I don't even get the malformed URL error, instead I get an uri one. When I run mtp-detect in a terminal, the phone is there. When I run solid-hardware5 list it's not. Unless solid sees it, kio doesn't know what to do with it.

If you have wifi you can use kde-connect as a workaround. Hopefully upstream will get mtp sorted out soon.

Can someone validate that it does indeed work when booting the lts kernel? Or I'll do it when I get back.

I'll try it with the LTS kernel and see what happens. Will update in ~10 minutes.

I've gone ahead with the LTS kernel and it seems this doesn't happen with it. It still acts a little weird, like the connection itself is unstable, despite me checking cables and both devices thoroughly, but it is working.

Works with LTS kernel, but as @Schyken said, it's intermittent. That's also a problem that was reported upstream back in 2013, with reports being added to the bug ticket right up to December of last year.

Seems to be a timing issue between detection/seeing if the device is still connected and KIO. Definitely upstream though.

Someone want to try this with both kernels to verify it works?

https://bugs.kde.org/show_bug.cgi?id=387454#c25

Basically change line 4 in /usr/lib64/udev/rules.d/69-libmtp.rules

ACTION!="add", GOTO="libmtp_rules_end"

to

ACTION!="bind", ACTION!="add" GOTO="libmtp_rules_end"

That works fine with kernel 4.15.17-65.current

Not sure what this did but it helped ?

Likely will be that the kernel from 4.14 now binds rather than adds devices...
