Reproducible crash with v4.6 and keyword completion

[curio77]

Hello,

 

When adding keywords to images by typing into the input field and maneuvering the suggestions list with the keyboard, Daminion v4.6 (#1481) will frequently crash when paging using [PgDn]. This results in an exception dialog with information like the following example:

 

System.ArgumentOutOfRangeException: InvalidArgument=Value mit dem Wert 50 ist für SelectedIndex ungültig.
Parametername: SelectedIndex
  bei System.Windows.Forms.ListBox.set_SelectedIndex(Int32 value)
  bei PicaJet.Daminion.GUIComponents.PropertyInspectorEx.IntelliSenseClass.OnTextBoxPreviewKeyDown(Object sender, PreviewKeyDownEventArgs e) in c:\DaminionAuto\Code\GUIComponents\Controls\PropertyInspectorEx\IntelliSense\IntelliSense.cs:Zeile 735.
  bei PicaJet.Daminion.GUIComponents.PropertyInspectorEx.TagEditors.TextBoxPro.OnTextBoxPreviewKeyDown(Object sender, PreviewKeyDownEventArgs e) in c:\DaminionAuto\Code\GUIComponents\Controls\PropertyInspectorEx\TagEditors\TextBoxPro.cs:Zeile 1032.
  bei System.Windows.Forms.PreviewKeyDownEventHandler.Invoke(Object sender, PreviewKeyDownEventArgs e)
  bei System.Windows.Forms.Control.OnPreviewKeyDown(PreviewKeyDownEventArgs e)
  bei System.Windows.Forms.Control.PreProcessControlMessageInternal(Control target, Message& msg)
  bei System.Windows.Forms.Application.ThreadContext.PreTranslateMessage(MSG& msg)

 

Steps to reproduce:

 

1. Select an image.
   
2. In the properties panel, focus the input field for keywords and start typing some existing keyword.
   
3. When the suggestions popup is displayed, page downwards using [PgDn]. In most cases, Daminion will crash towards the end of the list.
   
4. If it does not crash, retry with some other keyword.
