comment:
:I plugged in an iPhone 4, and NetworkManager showed up as trying to add a connection, for the Wireless Access tethering.
:
:When plugging iPhone 4 into other devices, this normally works fine. However, with my Fedora install, the Network Manager animated "connection circle" icon appeared, then the crash message appeared.
:
:It is possible at the same time the iPhone was also trying to mount as a storage device, but this does not appear in the removable storage list on my machine
