Bernhard, that's it! I checked: # dpkg -S /usr/local/lib/libimobiledevice.so.6 libimobiledevice: /usr/local/lib/libimobiledevice.so.6 # dpkg -S /usr/lib/x86_64-linux-gnu/libimobiledevice.so.6 libimobiledevice6:amd64: /usr/lib/x86_64-linux-gnu/libimobiledevice.so.6 # But I noticed the libimobiledevice package isn't in sid anymore. I wonder if it's been deprecated. I removed it, and now only have libimobiledevice6 installed. And now: # usbmuxd # No segfault! As a user: $ ifuse /media/iphone/ $ ls /media/iphone/ BooksDCIM iTunes_Control PhotoStreamsData Radio CloudAssets Downloads PhotoData Purchases Recordings $ ideviceinfo ActivationState: Activated ActivationStateAcknowledged: true BasebandActivationTicketVersion: V2 [... etc ...] $ fusermount -u /media/iphone/ $ It turns out this old libimobiledevice package was interfering. Thank you, Bernhard and Yves-Alexis for your help! I'm so glad to be able to mount this phone and get the photos off after so many months... Please close this bug as fixed.
