Are you by chance using Compiz as window manager? 

There seems to be a problem with Compiz and KDE applications at the moment:

I'm not using Compiz, but I found that KDE Desktop Effects settings act on this bug: if in KDE settings I set Rendering Engine to XRender the bug disappear, while setting to OpenGL 2.0 or OpenGL 3.1 causes kwrite to crash as soon as you click on "Save as" button.

Comment 4 Mattia 2015-12-23 17:25:49 UTC

Another strange thing I've just noticed: if I create a new text file in Dolphin (right click - create - text file) and then I open it with kWrite the application doesn't crash when I click on "Save as" button (even with OpenGL as rendering engine).
However if I just open kWrite and click on "save as" it crashes.

Comment 6 Mattia 2015-12-27 14:23:49 UTC

I think there is some problem between Framework and OpenGL rendering: it's not only Kwrite to have problems, I can also see other software crashing while opening the "save as" window (tested with QT Creator) or "Open" window (tested with Marble).
