Comment 1 mwc85.23yp 2018-02-08 05:21:08 UTC 
I'm also seeing this problem on Fedora 27 (rpm: juk-17.12.1-2.fc27):
287> juk --version
juk 17.12.1
288> 

Trying to expand any menu item in "Collections List" results in crash. Looks playlist-related:

org.kde.juk: void LyricsWidget::receiveLyricsReply(QNetworkReply*) Unable to find lyrics in text

Thread 1 "juk" received signal SIGSEGV, Segmentation fault.

Comment 2 Michael Pyne 2018-02-08 05:24:16 UTC 
Thanks for the report, I'll take a look later this week when I return from travel.  I don't actually use the Tree View myself so it's quite possible that it didn't survive the port to KF5 in quite the way it was supposed to.
Comment 3 Michael Pyne 2018-02-11 00:05:49 UTC 
Git commit 5982cede97993bf6cb81b80ef136b42c032382a5 by Michael Pyne.
Committed on 10/02/2018 at 22:46.
Pushed by mpyne into branch 'Applications/17.12'.

Avoid crash on tree view mode by disabling tree view mode :(

I can't decipher the brokenness here in a way that will lead to a quick
fix, so disable the broken feature for now to avoid causing needless
crashes for a feature that currently doesn't work at all.
