SUMMARY

Plasma shell and other KDE applications using too much memory:

```
wangbin   672864  0.8  7.2 6562240 3595144 ?     Ssl  Nov16  17:03 /usr/bin/plasmashell --no-respawn
wangbin   760286  0.2  5.7 5532672 2816472 ?     Ssl  Nov16   5:07 /usr/bin/krunner --daemon
wangbin   672846  0.2  5.0 3789384 2502220 ?     Ssl  Nov16   5:33 /usr/bin/kded6
wangbin   672916  0.2  4.8 3135384 2375968 ?     Ssl  Nov16   4:29 /usr/lib/org_kde_powerdevil
```

As shown above, plasmashell uses more than 3G memory while krunner and org_kde_powerdevil both uses more than 2G. Dolphin also used more than 2G before I close it.

STEPS TO REPRODUCE
1. Use KDE for more than 1 day.

OBSERVED RESULT

Memory usage for Plasma shell and other KDE applications increased a lot. Especially weird for applications like "/usr/lib/org_kde_powerdevil". 

EXPECTED RESULT

It shouldn't use so much memory.
