The first time I bring up Kdevelop with the Kate editor I can select some text in the code and press Ctrl-f to use the selected text for Find (i.e. search the code for the next or previous instance of the text).

Subsequent selections of text do not use the selected text for Find, but instead I only get the first selection.
I have to use Ctrl-c, Ctrl-v to get new text in the Find selection box. 

Reproducible: Always

Steps to Reproduce:
1. Highlight text with mouse
2. Press Ctrl-f to use highlighted text for Find
3. Try this again

Actual Results:  
Works first time, not subsequent times.

Expected Results:  
Should work every time.
