--- Comment #5 from Luca Giambonini <luc...@bluewin.ch> ---
I think is somehow related to this issue.
Applications 16.04.0, KF 5.21

I'm able to replicate the issue 100% of the time.
1) open a folder containing pictures in dolphin, al least 30 images (50MiB in
total, hi-res). The preview must be enabled
2) enable the slipt window and disable it immediately, repeat that for 20 times
very quickly
3) when you finish step 2) you should have a non splitted window, then press
the preview button... crash
