crash when close window(memory release)

[hament]

hello , in my project, i used NSTextView-LineNumberView, the textview is on a NSWindowController,when i close the window , the app must crash, and the Xcode log a location is "[NSTextview rulerView: willSetClientView:]"

actually, the rulerView: willSetClientView: method should be invoke by NSrulerview.

Here is my demo : http://yunpan.cn/cc99hU9TwQ8Wz （提取码/fetch code：8fce）

@hament hello, I meet the same problem,too. Did you solve it ?

@afantree en ,you can subclass a NSTextview, and add a empty method

• (void)rulerView:(NSRulerView *)aRulerView willSetClientView:(NSView *)newClient{
  }

in it to avoid the crash problem.
However I use another tool ASKLineNumberView in github to replace LineNumberRulerView

@hament yeah，Thanks for your method ，I solve it .
