Calling -[NSTableView moveColumn:toColumn:], interleaved with -[NSTableView addTableColumn:], can crash in -[NSTableHeaderData _didMoveFromColumn:toColumn:animated:].

To reproduce: Create a view-based table view (not sure if view-based is significant) with one column in IB. Then the following sequence will crash:

[tableView addTableColumn:[self createColumnWithIdentifier:@"1"]];
[tableView moveColumn:1 toColumn:0];
[tableView addTableColumn:[self createColumnWithIdentifier:@"2"]];
[tableView moveColumn:2 toColumn:1];


But this alternate sequence doesn't crash:

[tableView addTableColumn:[self createColumnWithIdentifier:@"1"]];
[tableView addTableColumn:[self createColumnWithIdentifier:@"2"]];
[tableView moveColumn:1 toColumn:0];
[tableView moveColumn:2 toColumn:1];

A sample project that shows the issue would expedite things. A crash log would be helpful too.

To locate the crash log(s), please check the following locations (you may need to do this in a Terminal window, rather than using Finder): 

~/Library/Logs/DiagnosticReports 
/Library/Logs/DiagnosticReports 

If you are not able to locate any crash report information in either of these locations, please check the /var/log/system.log for any relevant 
error messages from "crashreporter" or "crashdump".

Please upload and attach all relevant files to this bug report.

Sample project is attached. Note that the only code necessary are the four lines I submitted IN THE ORIGINAL REPORT.
