Select area doesn't work on first run

[Wes]

To reproduce:
 - With "Select area to grab" selected as default:
 - In a new session, open Screenshot, "Take Screenshot"

Actual:
On first run, screenshot program closes, area cursor is not displayed, nothing happens
Have to reopen the program for area screenshot to work.

This is happening consistently after every login.

Expected:
Select area works on first run.
