I usually have some places to my document folders on my external HDD. Sometimes I forget to mount the HDD before accessing the folder. Under certain circumstances (see steps to reproduce), dolpin deletes folders from the places panel.



Reproducible: Always

Steps to Reproduce:
1. Open dolphin, click on the document folder in the places panel
2. Dolphin shows a error that the folder is not existing in /media/username/External HDD/documents (that's OK)
3. I mount the HDD by using the tray menu
4. Because of some USB bugs of my motherboard (too lazy to do BIOS update), the external HDD loses connection while mounting (see dmesg log)

Actual Results:  
The document folder disappears from panel, other folders pointing to the external HDD are still there

Expected Results:  
Nothing should happen until I refresh the folder manually.

Dolphin log after:

1) Doing the steps, I described above
2) Plugging-out and plugging in the external HDD and mounting the device properly. I also readded the missing document folders to the panel.
