Local QML Image fails to load in offline mode on Symbian

This bug only occurs when I am using an external library that does some networking setup, but it still seems like an unhandled error case in QML.

1. Set the phone to "Offline" mode and disallow all network connections.
2. Create a QML Image with source set to an absolute local path of a file in the Symbian file system (ex. C:/Data/image.jpg).
3. Image is not shown and the following error is logged: QML Image: Network session error

It looks like QML Image treats the local path as a network path only under these circumstances.

Observations:
1. The bug does not occur if I use a URI like file://C/Data/image.jpg
2. The bug does not occur if I do not use the external library.
3. The bug does not occur if I have a valid network connection.
