Description RobinK 2020-01-25 01:56:38 UTC 
Application: plasmashell (5.17.90)

Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 4.12.14-lp151.28.36-default x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.1"

-- Information about the crash:
- What I was doing when the application crashed:

I'd just updated a number of libQT5 packages (19 of them) to level 5.14.0-lp151.3.2

Now Dolphin doesn't work at all.  Trying to open it from the command line gives me this:

Icon theme "MacUltimate_Leopard" not found.
Icon theme "Lero_0.3" not found.
Icon theme "Papirus" not found.
Segmentation fault (core dumped)

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
