Cropping

I have an issue with cropping an image. When I go to crop, I can drag the box around what I want, but once I let go of the mouse it uncrops the image. The only way to actually get it to crop is to drag the cursor outside of the entire Preview/Crop window so the mouse unclick doesn't register in the crop window. Unfortunately that doesn't let me take out a border on an image or crop the image smaller from all 4 sides, just 2.

The relevant section of my log:

442480|TRACE|Picture |setCropTo null
445373|TRACE|Picture |setCropTo java.awt.Rectangle[x=27,y=43,width=603,height=932]
445374|TRACE|Picture |setCropTo null
477378|TRACE|Picture |setCropTo null
479925|TRACE|Picture |setCropTo java.awt.Rectangle[x=29,y=43,width=600,height=930]
479926|TRACE|Picture |setCropTo null
480566|TRACE|Picture |setCropTo null
490997|TRACE|Picture |setCropTo java.awt.Rectangle[x=27,y=40,width=602,height=933]
490998|TRACE|Picture |setCropTo null

Notice that the first "setCropTo null" is resetting the crop like it should so I can recrop (well it shouldn't do that if you are adjusting an already cropped image. Then it sets the crop and sets it right back to null.

I'm running GR under Ubuntu Dapper 6.06.
