            Bug ID: 476986
           Summary: Dolphin hoards MTP devices.
    Classification: Applications
           Product: dolphin
           Version: unspecified
          Platform: Archlinux
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: stillflyinginc at gmail.com
                CC: kfm-devel at kde.org
  Target Milestone: ---

If Dolphin has been opened once since the computer started, it will hoard all
MTP devices connected, even if Dolphin is closed. Other programs that utilize
MTP such as Strawberry Media Player, Partition Manager, gMTP, all of 7 other
Media Players I tried - none of them can utilize MTP devices once Dolphin has
been launched. The device will show up of them if selected, but trying to
connect to them will fail. Attempting to connect before Dolphin has ever been
started works, uninstalling Dolphin makes it so other programs using MTP can
connect and function as expected. Killing Dolphin via terminal or System
Monitor does not resolve the issue.

NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.

STEPS TO REPRODUCE
1. Start Computer
2. Open Dolphin File Manager
3. Connect MTP device
4. Attempt to connect and use any other program to the MTP device, even after
dismounting it in Dolphin. The other program recognizing the MTP device does
not count - it is when the other program tries to read or access the device
that it fails.

OBSERVED RESULT
Other programs cannot ever use MTP devices

EXPECTED RESULT
Closing thunar and making sure it is not running via System Monitor should
allow other programs to access MTP devices. There should be an option to
disallow Dolphin from ever auto-mounting MTP devices.
