Comment 1 for bug 1513830

Similar problem here (almso wily). A Plasma crash and install -symbols of crash assistent was not completely sucessful. Assistant listed those as missing:

/usr/bin/plasmashell
/usr/lib/x86_64-linux-gnu/libQt5Core.so.5
/usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5
/usr/lib/x86_64-linux-gnu/libQt5Quick.so.5

AFAIU without complete set of libQt5core dbg symbols it's hard to report any KDE related problem.

P.S. Here's an example of unresolved symbols
