Dear Maintainer,

   * What led up to the situation?

I'm trying to connect my Galaxy Nexus (Android 4.1) and browse some the
filesystem.

   * What exactly did you do (or not do) that was effective (or

     ineffective)?
Plug my phone, after new device is fired, trying to browse it
2 directories appear :
 - Mass Storage Camera
 - Samsung Galaxy Nexus/Galaxy S (i9250, Android 4.0 updates@usb:001,006)

   * What was the outcome of this action?

If I try to browse "Mass Storage Camera" folder :
An unknown error 150 is fired (sorry it is in french) :
"Code d'erreur 150 inconnu
Mauvais paramètres
Veuillez envoyer un rapport de bogue détaillé à http://bugs.kde.org."

   * What outcome did you expect instead?

List of available folders !

I have tried with gMTP and MTPfs (fuse module) and it works more or less (lots
of freezing, segfault, errors when copying files)...

I don't know if it is from kio or libmtp9 or dolphin...

Thanks to take care of that trouble.

Kind regards

Mourad

Looking at the most recent entry in
http://packages.debian.org/changelogs/pool/main/libm/libmtp/current/changelog
leads me to think you might have more luck with the libmtp from Unstable.

I have a Samsung Galaxy S 3 and I have, eventually, gotten it working on
Kubuntu.  The path that works for me is (with the phone set to MTP device:

camera:/USB PTP Class Camera@usb:/store_00010001/

With it set to PTP device, this path sometimes works:

camera:/USB PTP Class Camera@usb:002,015/store_00010001/

The KIO for camera provided by Kamera is, well, not the most elegant code
you'll ever see is the kindest way I can put it.  That doesn't work every
time, sometimes I get a crash.  I haven't filed a bug on bugs.kde.org yet, but
it's definitely an upstream bug.

If I follow the other path:

camera:/Samsung GT-P7510/Galaxy Tab 10.1/S2/GT-N7000/Galaxy Nexus@usb:002,012/
it never works.  Either I will get the same KIO crash (The process for the
camera protocol died unexpectedly.) or your error 150.

I also ran into a problem at one point of having been a bit too aggressive at
disabling services off the phone and I had to re-enable one (I think it was
DirectShareManager).  I don't know if yours is the same.

It seems it's a bit of a mess and I think it's a KDE mess as Kamera is rather
unmaintained.

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

It used to cause problems years ago, and a week ago (i don't need it often) after an update in debian testing - it restarted.
It simply refuses to mount the MPT-device. I can lucky me, access it through gwenview.
   * What led up to the situation?
A recent update i assume (maybe with KDE or systemd).
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Grab the image through gwenview - that went smoothly.
   * What was the outcome of this action?
   * What outcome did you expect instead?
