• OK, if you need this working, it's simple to fix.
  Go into your project folder to

  build/iphone/Classes/

  and edit the file TiUIiPadPopoverProxy.m

  change the code

  -(void)setLeftNavButton:(id)item withObject:(id)properties
  {
      ENSURE_SINGLE_ARG_OR_NIL(item,TiViewProxy);
      [self replaceValue:item forKey:@"rightNavButton" notification:NO];
      [self refreshTitleBarWithObject:properties];
  }
  

  to

  -(void)setLeftNavButton:(id)item withObject:(id)properties
  {
      ENSURE_SINGLE_ARG_OR_NIL(item,TiViewProxy);
      [self replaceValue:item forKey:@"leftNavButton" notification:NO];
      [self refreshTitleBarWithObject:properties];
  }
  

  delete the build/iphone/build/ folder to force Titanium to recompile and you're set :)

• OK, this is fixed in the upcoming 1.4 :)
