Prevent Horrendously Wide NSBrowserCell Tool Tips
===

I am setting my `NSBrowser` matrix cells' tool tips with the below code:

    - (void) browser:(NSBrowser *)sender willDisplayCell:(id)cell atRow:(int)row column:(int)column  {	
        NSMatrix *matrix = [sender matrixInColumn:column];
        NSLog(@"'%@'", [cell stringValue]);
        [matrix setToolTip:[cell stringValue] forCell:[matrix cellAtRow:row column:column]];    
    }

This results in wonderful tool tips, most of the time.

When hovering some cells, however, the tool tip expands to a grotesque width, transforming an otherwise delightful experience into one that is as hideous as it is confusing. Evidenced in the below screenshot.

The output for the cell triggering the heinous tool tip pictured above is:

    'gnome-1.1-tb-linux.jar'

What could be causing these seemingly random atrocities - am I missing something?
