Stack trace with debugsymbols

Recently I noticed that plasmashell reports a crash in system tray after
logging out and back in again a few times. At first plasma still seems to be
working, but what's noticable is that all applications tend to start up A LOT
slower.
It never happens on first login, but after a few logins its easily
reproductible even in a VirtualBox VM.
I'm pretty sure the crash is not related to a graphics driver as it happens on
both VirtualBox drivers and proprietary NVIDIA drivers.
It may happen due to some patches applied to plasma5-desktop, KDE Frameworks or
libqt5-base as I'm having great difficulties reproducting it in Arch Linux,
however, it may also be an upstream bug Arch Linux has already patched, so no
guarantees there.

I've attatched a full stack trace with all debugsymbols installed, maybe that
helps.

Thanks for your efforts,
