Issue
Returning to the file browser when not connected to wifi causes a crash and a popup asking if you want to connect to wifi.
Connected to wifi, back to normal
Steps to reproduce
Turn off the device wifi.
Open any document in any format.
Click on the File Browser (second button from the right in the top menu bar).
The process crashes, clicking on any area of the screen will indicate that the process is not responding. Wait half a minute for the process to return to normal and go back to the file browser.
At this point, Koreader will pop up two overlapping windows, prompting that wifi is not turned on and asking if you want to turn on wifi.
