Description:
This is my first attempt at filing a bug, if i am missing any critical info ask me, i will reply ASAP.

1. What is the problem?
"open" window not responding which you get under "template" window by clicking on "import". 

2. What is my Work Around?
Now, since i cant click on anything in "open" window, i tried to close the "Template" window which is the parent window which generated this ("open") child window. And to my surprise, it didnt close the open window plus it somehow made the "open" window responsive again.




Steps to Reproduce:
1.In LibreOffice Writer -> File -> Templates -> Manage Templates -> Import -> Select Category-> open. 


Actual Results:  
Now this "open" child window is not responding i.e. you cant click anything including close or cancel button. However you can close it by pressing ESC key.

Expected Results:
It should help in locating "template" by letting the user browse the file system.


Reproducible: Always

User Profile Reset: No
