SUMMARY
File renamed while in search mode: displayed filename of the renamed file is not updated in search results if search bar is closed and reopened.

STEPS TO REPRODUCE
1. open a folder in Dolphin
2. press CRTL+F and search for a file in that folder - e.g. filename_1
3. rename the file - e.g. filename_2
4. close the search bar
5. press CRTL+F to reopen the search bar and search for the same file

OBSERVED RESULT
filename displayed in search result is 'filename_1' and it was not updated to 'filename_2'. As a consequence opening it results in an error. You need to force Dolphin to update the list by pressing F5.
