Kiori's solution didn't work for me. I ran mtp-detect 10 times, always failing with the same LIBMTP PANIC message as above.
Ubuntu 14.04, libmtp 1.1.6, Sansa Clip Zip (appropriate libmtp rules already present). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1247572 Title: Nokia Lumia 620 (WP8) fails to mount reliably via gvfs-mtp in nautilus Status in GVFS: Fix Released Status in Nautilus: New Status in gvfs package in Ubuntu: Confirmed Status in nautilus package in Ubuntu: Invalid Bug description: Summary: You have to run mtp-detect in terminal until you get output similar to the excerpt in the steps to reproduce section, then you can connect via nautilus as usual. ----- I just got a Nokia Lumia 620 as a backup phone. I'd say I can mount my Nexus 4 reliably with Ubuntu via nautilus using gvfs-mtp. Users with Android devices like the Nexus 4 still get error messages on a regularly basis of the device not being able to mount, but replugging the device mostly fixes the issue. However, the experience with the Lumia 620 is far worse (the desktop sometimes freezes) and the workaround I found to get the device to work very crude. I was prompted with a apport-collector window when nautilus froze during testing and send a report (this happend twice), but it didn't take me to Launchpad to open a report. I can also seen no bug regarding that topic that I am subscribed to. The Lumia 620 itself was added to libmtp with this report: http://sourceforge.net/p/libmtp/bugs/780/ ## Steps to reproduce: 1. Reboot (or cold boot) computer and phone. Login to computers destop and unlock the phone by entering PIN. 2. Plug the phone via USB into the computer. (Cable works with Nexus 4 or another Android device.) The phone will give a signal that it is connected to the computer. 3. Try to open the phone in Nautilus. My desktop either freezes (cold boot) here or nautilus hangs (reboot). 3.a) If nautilus hangs: Open a terminal with Ctrl+Alt+T and kill nautilus with xkill. 3.b) If your desktop froze: Go to a virtual terminal with Ctrl+Alt+F1. 3.c) If you just get an error message: Open a terminal with Ctrl+Alt+T and go to step 4. 4. Execute 'mtp-detect' (from mtp-tools package) from terminal (either via Dektop or virtual terminal). If you get one of the following messages wait a few seconds and try again. $ mtp-detect Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6 Listing raw device(s) Device 0 (VID=0421 and PID=0661) is a Nokia Nokia Lumia WP8.

Go to a virtual terminal and do 'sudo service lightdm restart'. Login again, you hear the phone reconnecting to your computer and should now be able to open your phone in nautilus seeing the phones internal storage and the SD card (if there is) als sub devices. 6. Unplug the phone from the computer and start with step 2 if you want to connect the phone again. ## Additional information $ lsb_release -rd Description: Ubuntu 13.10 Release: 13.10 $ apt-cache policy gvfs gvfs-backends mtp-tools gvfs: Installed: 1.18.2-0ubuntu1 Candidate: 1.18.2-0ubuntu1 Version table: *** 1.18.2-0ubuntu1 0 500 http://de.archive.ubuntu.com/ubuntu/ saucy/main amd64 Packages 100 /var/lib/dpkg/status gvfs-backends: Installed: 1.18.2-0ubuntu1 Candidate: 1.18.2-0ubuntu1 Version table: *** 1.18.2-0ubuntu1 0 500 http://de.archive.ubuntu.com/ubuntu/ saucy/main amd64 Packages 100 /var/lib/dpkg/status mtp-tools: Installed: 1.1.6-2 Candidate: 1.1.6-2 Version table: *** 1.1.6-2 0 500 http://de.archive.ubuntu.com/ubuntu/ saucy/universe amd64 Packages 100 /var/lib/dpkg/status To manage notifications about this bug go to: https://bugs.launchpad.net/gvfs/+bug/1247572/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
