OK, that makes sense, thanks for reminding me on how this works.

I'll now add some unittests to check your fixes before they can be merged.

> Fix 1: When creating a new file, if a file with the default name already exist then a new name is suggested by *KIO::suggestName*. Now this works fine until the scheme of file's url is "file" but in case the scheme is "desktop" (*like when the url in dolphin is set to desktop:/ or "Folder View Settings > Location" is set to desktop:/*) then the check for file's existence fails because *QFile::exists* doesn't understand the "desktop" scheme. So *KIO::suggestName* is not called and no new filename is suggested in case a file with the same filename already exist. To fix this i used *KNewFileMenuPrivate::mostLocalUrl* in *KNewFileFileMenu::executeRealFileorDir* which will resolve "desktop:/" to the user's desktop path.

> Fix 2: If a user tries to create a new file and proceeds with the default filename then the file created will have no extension. This happens (*inside KNewFileFileMenu::executeRealFileorDir*) because the filename is read from the *Name* section of the desktop file. To fix this, read the URL(the url is in *templatePath*) from the desktop file, determine the file extension from there and append it in the filename.

> Fix 3: Fix for the bug https://bugs.kde.org/show_bug.cgi?id=363673 . The bug occurs because KPropertiesDialog is initialized (*inside KNewFileMenuPrivate::executeOtherDesktopFile*) with path of a resource file. Now KPropertiesDialog only show properties if the file is a local file(i guess). Thats why  clicking on "Link to Application" and then clicking 'ok' shows an error message . To Fix this i used QTemporaryFile to copy the contents of the application template shipped with kio and then initialize KPropertiesDialog with the temporary files' path.
> (I added KNewFileMenuPrivate::mostLocalUrl here to ensure new filename is suggested when inside "desktop:/".)
> (The temporary file created here must be deleted so i also added QFile::remove to *_k_slotOtherDesktopFile and _k_slotAbortDialog* so that whether or not the user creates a Link to Application, the temporary is always deleted)
