After deleting crash reports via "Problem Reporting" tool, I get continuous reports like: xdg-document-portal: unique: 6, opcode: STATFS (17), nodeid: 1, insize: 40, pid: 2578 xdg-document-portal: unique: 6, success, outsize: 96 where the pid is for ksysguardd This always (and only) happens when a crash is deleted as noted above.
Appears resolved in recent update.
