Please describe the problem:
The dialog window does not expand to show the advanced options, instead the text is printed over top of the buttons at the bottom.

Steps to reproduce:
1. Open GIMP;
2. select File->New; 
3. Click the 'Advanced Options' item in the 'Create a New Image' dialog that pops up.  


Actual results:
The dialog window does not expand to show the advanced options, instead the text is printed over top of the buttons at the bottom.

Expected results:
Dialog box to expand to include the advanced options

Does this happen every time?
Just the once so far.  It happened after I had changed the width and height from 640x480 to business card size (95.25mm x 57.15mm).  Could not reproduce in same session after I had manually enlarged the dialog box.

Other information:
Can resize the dialog box manually to see the options clearly.
