plasmashell log

It seems there's a memory leak in plasma's launchers. It happens both on
Application Dashboard and Application Launcher. Steps to reproduce:

1. open KSysGuard and filter plasmashell in the processes.
2. launch Application Launcher and browse the application menus repeatedly, and
watch as ram usage increases
3. after a while, close the launcher, open it again, and repeat step 2

This keeps increasing plasmashell's ram usage unstoppably. After a day of work
I usually have plasmashell consuming about 1GB ram. Killing plasmashell and
starting it again is a workaround.

I'm not sure if this can be related, but I have a nvidia card (GTX 970).

I posted plasmashell journal in the attachment. Please let me know there's
another relevant log to post. Also, I recorded a video showing this issue in
action: https://youtu.be/9D4TfWE1_vk
