[Dextrose] [sugar mainline PATCH] sl#3605: Do not rely on 'mountpoint' property being present in the metadata per entry. Instead use the global API.

[ajay at activitycentral.com]

From: Ajay Garg <ajay at activitycentral.com>

Following are the steps to reproduce the issue ::

a)
Ensure that the "Journal" and "Documents" are empty.

b)
Copy a file (I tried with a mp3) to a USB drive, from a non-XO machine.

c)
Insert the USB drive in the XO.

d)
Copy the file (of step b) ) to "Documents" folder.

e)
View Details of the copied entry (in "Documents").

f)
There should be the exception in the logs. Moreover, the "Description" field should be empty in the "Details View" (this field ought to be "/media/<name of USB drive>").
