Comment 21 for bug 1502556

memsys, how did you create that valgrind output?

most importantly, how did you close valgrind/plasmashell.
Almost all these traces are just in Qt and it seems unlikely that's the problem.

can all of you above try removing applets to see if we can pinpoint one causing a problem.

Can you all above tell me what graphic card you're using + driver versions.
