Description David Solbach 2010-07-05 23:33:45 UTC 
Application: amarok (2.3-GIT)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.31.12-0.2-default x86_64
Distribution: "openSUSE 11.2 (x86_64)"

-- Information about the crash:
The attached stack trace shows a crash that happened reproducibly when removing a media player (in my case the N900) while amarok was runnning.

When the media player was connected, the removable devices manager showed up and I chose "open in dolphin". Amarok recognized the N900, which was configured before, and showed it beneath my local connection. it wouldn't show it's media files, however...

When disconnecting the N900 (by pulling the USB cable) it crashed.

I'm using Amrok 2.3-GIT from opensuse build service. build date 20100705

The crash can be reproduced every time.

 -- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

New crash information added by DrKonqi

amarok (2.3.1) on KDE Platform 4.4.90 (KDE 4.4.90 (KDE 4.5 RC1)) using Qt 4.7.0

- What I was doing when the application crashed:
I had just waited about one hour for amarok to finish scanning my external hd for my music collection. After the hd activity had stopped for about 10 minutes, and no file showed in amarok, I tried clicking the eject button.

- Unusual behavior I noticed:
Amarok crashed

- Custom settings of the application:
None, started with a clean configuration.

New crash information added by DrKonqi

Hi, I'm attaching my crash to this bug report because both the circumstances and the backtrace appear to be similar. In my case, amarok crashed just after unmounting my USB mp3 player through the device list applet on the panel.

amarok (2.4-GIT) on KDE Platform 4.5.4 (KDE 4.5.4) using Qt 4.7.1

- What I was doing when the application crashed:
Removing the USB media device (my Samsung Jet phone, in Mass Storage mode)...

but that crash isn't caused by adding or removing a device.  it is triggered even when the device is mounted before launching Amarok, and without removing the device.  either that's not a dupe or this bug's title should be changed accordingly.
Comment 10 Ralf Engels 2011-03-05 15:37:37 UTC 
MediaDeviceHandler is given to the thread but no apparent code ensures that the handler is not deleted during the running of the parser thread.

This is a bigger change to fix.
Comment 11 Myriam Schweingruber 2011-11-15 07:56:17 UTC 
Is this still valid?
Comment 12 Myriam Schweingruber 2012-01-01 14:37:46 UTC 
Reproducible with Amarok 2.5
Comment 13 Matěj Laitl 2012-01-03 09:50:03 UTC 
I doubt this is reproducible, Handler::UmsReadCapability was removed before 2.5.0. Myriam?
Comment 14 Myriam Schweingruber 2012-01-03 19:47:51 UTC 
Darn, I should have looked better at the backtrace I got.

Closing, since the incriminated Handler is not here anymore.
Comment 15 Matěj Laitl 2012-02-05 23:32:31 UTC 
Changing NEEDSINFO → RESOLVED so that his doesn't pop in searches.
