When using the "type to skip to folder" feature, it is working only on the firstly opened folder. Than it stops working.

Reproducible: Always

Steps to Reproduce:
1. Open Doplhin window
2. Type few first letters of folder you want to open
3. The folder is selected (so the feature is working there); pressing eneter opens it
4. I want to repeat step 2 (type leters to select) for the newly shown subfolders, but it is not working.
Actual Results:  
After typing the letters, none folder is selected, even if folders beginning with the letters pressed obviouslly exists there.

Expected Results:  
The folder should be selected.

It stopped working after KDE update from 4.8.1 to 4.8.2.

I beleive it is somehow related to lower/uppercase. I have e.g. folders "Desktop" (beggining with D) and "download" (begginning with d). When I press "d" (lower one) following with "e", it jumps (correctly) to the "Desktop" item. But now I am not able to jump to the "download" folder, even if i "deselect" the Desktop folder. The lowercase "d" now stops working.

Another weird thing - when the window lost focus, and then it is returned, it is working again properly (until next folder is selected).
