Bug 348221

The text input field in Gwenview's File > Save As... dialog behaves badly.

Reproducible: Always

Steps to Reproduce:
1. Open an image named "something.jpg" in Gwenview.
2. Choose File > Save As...
3. Try to rename it "new.jpg" by typing in "new".

Actual Results:  
Gwenview dialog appears.
BUG 1: The dialog title bar is just named "Gwenview", I would expect it to be named "Save File — Gwenview" like Dolphin.

In the Name field, "something" is highlighted and the extension isn't (good).
The 'n' replaces the selection so the filename is now "n.jpg" (good).
But BUG 2: the ".jpg" becomes the selection. So the next letter you type overwrites it, and you lose the extension, the file name is now "ne".
BUG 3: Press Ctrl-Z and there's no Undo; right-click, and the context menu has "Undo" but it's grayed out.

It's even worse if you're trying to prepend something, e.g. to change "IMG201505.jpg" to "crop_IMG201505.jpg".  You press left arrow to move to the start of the Name field, press 'c', everything following is highligted, and then the filename is "cr" and you've lost the original name if you don't press Cancel.

You have to cancel and repeat to get back to the original name.

Expected Results:  
Don't select the extension after I start typing.
Do enable Undo/Redo.

I opened up Kate and saved a file in that, and it had the same behavior. So this seems a more general failing. (I don't know how to change this bug report to a more general component.)  Dolphin's inline file Rename works fine.

I'm marking this Major because anyone with years of experience using File Save As is going to lose file names or extensions.

This is a pretty stock Kubuntu 15.04 but I'm  using the PPA for more recent KDE software.
