mtp-server crash when transferring music on #15

[Alan Pope 🍺🐧🐱 🦄]

Trying to copy a load of music to my flo device. Same bunch of music I always copy over.
It crashed this time.
Usually it works fine, but with image #15 nautilus just stops while it's copying having done about 29 out of 585 files.

I get a pop up eventually.. "There was an error copying the file into mtp://[usb:001,067]/Nexus%207%20(2013)%20Wi-Fi/Music/Amy%20Winehouse/Back%20To%20Black%20(Deluxe%20Edition)."

Flashed back to utopic image #2 and it's broken there too.

Status changed to 'Confirmed' because the bug affects multiple users.

This is still broken in #104. Craps out after 44MB or so.

http://paste.ubuntu.com/7726525/ is what i get from mtp-server.log

[Peter Hultqvist (hultqvist)]

Broken for me on #119, flo, when I transfer from Ubuntu 14.04 using nautilus.

Every time at 2.1 GB I get the following message in the mtp-server.log

MtpServer.cpp:439] got unsupported command UNKNOWN

Nautilus says nothing, it stays pending at 2.1 GB

After this I need to reconnect the cable to get MTP working again.

[Mathieu Trudel-Lapierre (cyphermox)]

Unable to reproduce, I can copy both large total size of files (2.02 GB in a few folders of music) and a single large file (some 2.xGB) successfully with mtp 0.0.4+14.10.20140904~rtm-0ubuntu1.

Could someone seeing this issue try it again, with mtp debugging enabled (see below)? We need to figure out if there is a specific file name or combination of factors that causes this crash.

To enable mtp debugging:

1- vi /usr/share/upstart/sessions/mtp-server.conf
2- add "env GLOG_v=4" after the existing "env GOOGLE_LOGTOSTDERR" line.
3- disconnect the device from USB
4- reconnect the device.

I've not seen this issue again recently.
