Error message that makes no sense when trying to open a file that doesn't exists (from bookmarks for example)

[doutriaux1]

If I clicked on a bookmarked file that dopesn't exists anymore, I can still still click on "Load and close" and then get the following non-sensical error:

Traceback (most recent call last):
File "/lgm/ucdat/2013-01-02/vistrails/vistrails/gui/uvcdat/variable.py", line 520, in defineVarCloseClicked
self.getUpdatedVarCheck()
File "/lgm/ucdat/2013-01-02/vistrails/vistrails/gui/uvcdat/variable.py", line 560, in getUpdatedVarCheck
axisList = self.dimsLayout.itemAt(1).widget()
AttributeError: 'NoneType' object has no attribute 'widget'

We need to disable to "load and CLose" button until a variable is actually loaded

Verified as fixed. Note that the error message is written out to stdout/err so there is no feedback to the user unless they look at the log. Suggest using a GUI message box here.
