Version:           1.7 (using KDE 4.7.0) 
OS:                Linux

The problem I have found is that if you are in a directory and create a file in the same directory from a separate application, the name of the file is refresh in dolphin, but its size does not. However, if you remove the file, it disappears from the list, as expected.

PS: I have just upgraded to KDE 4.7.1 and rebooted my PC and check my problem persists.

Reproducible: Always

Steps to Reproduce:
1.- Open Dolphin in directory
2.- Open Konsole in the same directory
3.- From Konsole issue the next command: date >> date.txt
4.- Repeat the previous step many times
5.- Press F5 in dolphin to refresh the size of the file date.txt
6.- From Konsole issue: rm date.txt


Actual Results:  
Current size is not refreshed automatically and you have to manually press the key F5 to refresh it.

Expected Results:  
Current size should be refreshed automatically.
