The new apk you linked at that Phabricator page works. 

I have also attached the output of 'adb logcat' during a crash, while using the
version in the Play Store. I paired the devices with kdeconnect, enabled USB
debugging, opened kdeconnect, and then started the command. I immediately went
to my music player on my computer and played a music file with album art. After
that, I got a message that kdeconnect crashed (on my phone), and I ended the
'adb logcat' command.

suggested change?

You can download an Android apk at https://phabricator.kde.org/D12618
Can you try to install this and see if the app still crashes? You might get
prompted to first remove the currently installed KDE Connect app.

In case it doesn't work, it would be great if you could upload a log (connect
your phone by usb and run "adb logcat" on the command line, then wait for the
app to crash).

I've been able to reproduce it again. It seems to crash only if the song I'm
playing has album art associated with it. This is with Clementine.

Okay, this is really weird. I can't reproduce it any more. Tested with
Clementine and Rhythmbox. I haven't changed the versions of kdeconnect (on my
phone and laptop) or Clementine.

I'm using the qt5 branch of Clementine
(https://aur.archlinux.org/packages/clementine-qt5-git/). I'll try to reproduce
it with some other player, soon.

Checking the crash reports on the Play Store, I found a ClassCastException on
the following cast in AlbumArtCache.java:

connection = (HttpURLConnection) currentUrl.openConnection();

This crash is actually quite common, with 300 crashes in the past 7 days.

I'm not sure what's the cause though. The only other subclass of URLConnection
that can come from openConnection() is JarUrlConnection:

https://developer.android.com/reference/java/net/URLConnection

But I don't think we can get a JarUrlConnection there. I was trying to
reproduce the crash to see what kind of URLConnection we are getting there, but
it doesn't seem to crash on me.

What media player are you using?

I forgot to mention in my previous comment that, as far as I can tell, there
are no issues when I disable the 'multimedia control' plugin.
