crashes when retyping things AGS Editor

[eri0o]

Hello,

Since today I am getting two weird bugs that I either didn't have before or never noticed on the AGS 3.4.3.1 Editor. Note that I use AGS Editor on Ubuntu 18.04 (previously 16.04) through Wine, for years, but this has never been a problem.

Sometimes, when I try to rename a script and then cancel the action, I get the following error on the Editor.

Error: External component has thrown an exception.
Version: AGS 3.4.3.1

Code: ags

System.Runtime.InteropServices.SEHException: External component has thrown an exception.
   at System.Windows.Forms.UnsafeNativeMethods.CallWindowProc(IntPtr wndProc, IntPtr hWnd, Int32 msg, IntPtr wParam, IntPtr lParam)

   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Also when I replace some text on the code editor, when I rewrite the name of a variable by double clicking it to select and start typing, I get:

Error: Length cannot be less than zero.
Parameter name: length
Version: AGS 3.4.3.1

Has someone ever met those bugs? I have recently used the latest 3.5.0.14 release of the Editor and I think they don't happen there, but I think I didn't got they before on 3.4.3.1, so I think I have something funny somewhere on my project.

I have backups so currently I am trying to see if there was any state before where this didn't occur. I really don't remember having them.
