IOException crash when downloading to cloud synchronized folder

[lolfert]

I've found that the application will crash during downloads if the folder being written to is cloud synchronized. I imagine a check could be added prior to downloading to determine whether the file initialized is still writable. In the case that the file is being accessed by a program like google drive the download could be deferred.
