Bug 344525

In applications that depend on KF5-based version of kparts and that have a save-as dialog (ksnapshot, kate, gwenview...)
it is not possible to edit filenames as usual in the save-as dialog:
If you move the cursor to the left to edit characters of a given filename, then after inserting the first character all characters on the right side of the cursor become selected.
The consequence is that after typing a second character the selected ones are replaced by the second newly inserted character and are therefore deleted. (The extension if there was one is also deleted then.)

Difficult to explain, so here's an example:
The filename 'this-is-a-given-filename2.png' is the suggestion of ksnapshot when saving the second sceenshot  and you want to modify it to 'this-is-another-given-filename.png'.
Deleting (character '2') is never a problem. Then you move the cursor between 'a' and '-' and begin to insert. When 'n' is typed the string '-given-filename2.png' on the right side of it becomes selected and when you type 'o' then the selected string is replaced by 'o' and therefore deleted.

Trough this behaviour modifying filnames becomes very unergonomic, especially for series of files.

Expected behaviour: It should be possible to insert characters in filenames like in texts in a text editor.

Reproducable: always in different KF5-based KDE linux distributions. I tested with Manjaro 0.9.0 KDE 64-bit testing.iso, KaOS testing.iso and Kubuntu 15.04 alpha2 (Here only kate and gwenview are already KF5-based. After installing all package an kernel updates the installation became unusable.)
