GUI: SMART-information and selftests window unable to resize window to read text

Steps to reproduce:
* In the Gnome Disk Utility
* Select any drive supporting SMART
* click on the gear icon
* Choose SMART Info and Selftests
* Click on the dividing line between Attribute and Value
* Try to drag left or right in order to be able to read the Attribute
* Doesn't budge.
* Try to grab the bottom right corner of the window to increase it's size so you can read the darn thing.
* Doesn't budge.

The window seems to be stuck at 950x500 pixels making the contents of the window unreadable in languages with long words like Dutch and German.

Please let the user of the computer decide how large or small they want the window.
There is no such thing as one-size-fits-all in computer graphical interfaces.

Oh and see the screenshot for the example.

179 used-res...csk-total ?
181 program...unt-total ??

And before you say just mouse over.
tried that get the message:
"There is no description for Attribute 179"
Thanks but just make the window resizeable please.

Thanks!
