Matplotlib figures not working after Tkinter file dialog
Question: I'm using the following function which I found as a reply to [this
question](http://stackoverflow.com/questions/9319317/quick-and-easy-file-
dialog-in-python) to show a dialog window for file selection.

[ Edit: Turns out the distro differences here are merely because Matplotlib is
using gtk3agg on Fedora and TkAgg for drawing windows on each system ]

**On Fedora 18:** Everything works fine.

**On Ubuntu 12.10:** Matplotlib hangs after closing any figure displayed after
the file dialog. For example, in the code below, on Ubuntu I can never get to
the "made it" line. I am still able to type in the terminal, though nothing
happens. If I remove the file dialog, Matplotlib figures work as expected.

    
    
    import Tkinter, tkFileDialog
    import pylab
    
    def ask_for_config_file():
    
        print "Please provide location of configuration file."
    
        root = Tkinter.Tk()
        root.withdraw()
        file_path = tkFileDialog.askopenfilename()
    
        return file_path
    
    
    def main():
    
        config_file_path = ask_for_config_file()
    
        pylab.figure()
        pylab.show()
    
        print "Made it."
    

Any suggestions?


Answer: I just needed a `root.destroy()` at the end of the dialog function!
