SUMMARY
When i "de-minimise" dolphin clicking on the task-manager panel, it will not
appear for different seconds, AND will also freeze the "task-manager"

STEPS TO REPRODUCE
1. set a secondary hard disk to go sleep after some minute with sudo hdparm -S
1 /dev/sda (where 1 should be 5 minutes)
2. make sure the disk is mounted, i use fstab
3. wait for the disk to go sleep
4. open dolphin, all should be fine
5. minimize dolpin, all should be fine
6. click on dolphin on the task-manager to maximize, it will hang until the
disk restart (you can hear it spinning if mechanical)

OBSERVED RESULT
- dolphin not only does not open immediately
- the disk in wake up unnecessarily
- panel bar with task manager hangs until dolphin open

EXPECTED RESULT
- dolphin open immediately
- disk is not access unless clicking on the device
- dolphin should not hang other components
