-- Information about the crash:
This seems to be a recursive crash, originally I removed some notification entries, which resulted in huge memory consumption and a segmentation fault. Since then, plasma is repeatedly crashing, and it seems the crash handler is one part of the crash. The backtrace is just from one crash, I'm currently digging to  try to find the root cause.

Deleting ~/.cache/plasmashell didn't change anything

The reporter is unsure if this crash is reproducible.
