Summary: Plasma consumes all memory when showing calendar popup
Product: plasmashell
Version: 5.8.5
Platform: openSUSE RPMs
OS: Linux

Severity: major
Priority: NOR
Component: Calendar

complete valgrind log
I get this memory consumption bug ever since I created a TODO from within
KMail. What happens now is this. I click the clock plasmoid in Plasma panel to
show calendar popup and plasmashell process starts to consume a lot of memory
very fast until it uses all of 32 GiB of memory and is eventually killed by OOM
killer. I have run plasmashell via valgrind (valgrind --leak-check=full
--track-origins=yes --show-leak-kinds=all -v plasmashell) and these reports
appear to be related with this memory leak:
