Hello. I'm using KDE-Plasma in Arch Linux. Please help me !

I installed latest x,xf86-video-intel,sddm,plasma-meta and dolphin. It worked nicely.
But after I installed qt4, plasma crashes in many situations.
For example,I can't delete files with dolphin,emty Trash and so on.
I think conflict between qt4 and qt5 causes this problem.

I tested with Lenovo X1 Carbon (gen3) and MSI C236M.
Both are using intel HD graphics.

Arch Packages version are below;
linux46 4.6.3-1-ARCH
xf86-video-intel 1:2.99.917+674+g9154dff-1
plasma-meta 5.6-2
dolphin 16.04.2-1
qt5-base-5.7.0-1
qt4 4.8.7-9

This is Dolphin's error output.

Code: Select all

Application: Dolphin (dolphin), signal: Segmentation fault
