[MonoDevelop] Null reference exception in TextEditor.VAdjustmentValueChanged

[simozzer]

Hiya folks,

When using web projects I have experienced a recurring exception in
'/monodevelop/main/src/addins/Mono.Texteditor/Mono.TextEditor/TextEditor.cs'
which can be avoided with a small patch. My changes are highlighted in bold
below..


Alter the file:
/monodevelop/main/src/addins/Mono.Texteditor/Mono.TextEditor/TextEditor.cs


 void VAdjustmentValueChanged (object sender, EventArgs args)
                {
                        repaint = true;
//                              this.QueueDraw ();
//                              return;
                        if (buffer == null)
                                AllocateWindowBuffer (this.Allocation);

                        /* After calling AllocateWindoBuffer buffer still ==
null (because !IsRealized) */
                        if (buffer == null) return;

.....


Cheers

Mozzy
