(re)draw of pencil-drawing doesn't show all

[Google Code Exporter]

What steps will reproduce the problem?
1. open pencil standalone
2. new pencil
3. draw "desktop native ui widget - group box"
4. change name to mygroupbox
5. store pencil as "mypenciltest"
6. close pencil standalone
7. open pencil standalone again
8. recent documents
9. select "mypenciltest"

What is the expected output? What do you see instead?
the screen should be showing a box with a name but I see a box,with no complete 
border and without the text.
A fix is to change the vertical size to +1, and then -1. Then it draws the box 
again, and I see the box as should be.

What version of the product are you using? On what operating system?
Pencil standalone 2.0.5

Please provide any additional information below.
This happens with a lot of fields, like text entry for instance. So it seems, 
the draw (or redraw) doesn't seem to be working right when opening a 
pencil-drawing.
(BTW I love the product, so keep on doing what you do!)
