Configure Dolphin button results in a wxWidgets debug alert

[Landcross]

Doing the following (I'm using Dolphin 5.0 5667):

• Disable cheats
  
• Go to the properties of a game that has cheats
  
• Try to enable a cheat, a little warning should pop up with a 'Configure Dolphin' button
  
• Press that button...
  

Results in this error message:


I don't have a whole lot more to add besides that
