Description neo6238-kde 2011-11-21 20:49:26 UTC

Application: amarok (2.4.90)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-default i686
Distribution: "openSUSE 12.1 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:

This is really strange. I was testing the unmount feature in the latest beta. This works now. But then I was trying to test it again: Mounting with Dolphin and then clicking the little green tick (check mark) then amarok crashes.

But not in the first try, always in the second. This is reproduceable.

For the first try: It does not matter if you mount it before or after amarok started. In the first try clicking the green tick is no problem. After unmounting and trying a second time amarok collapes like this.

Hope this helps.

The crash can be reproduced every time.

I tried with my external USB drives and can't reproduce that. All 3 partitions are set to be used as collection when mounted.

amarok (2.4.90) on KDE Platform 4.7.3 (4.7.3) using Qt 4.7.4

- What I was doing when the application crashed:

Not clicking the tick, but opening one of the files via dolphin to try play it with amarok.

Comment 3 neo6238-kde 2011-11-22 17:36:28 UTC

Maybe it is some mounting/unmounting bug related to the MP3 player?

Right now I am trying to reproduce it with my other player, a Samsung U5:
That does not work. Because I cannot remount it.
You do not need to click the tick, because it scans the player after mounting automatically.
After unmounting this player, it disappears in the devices widget and in /dev. (That seems to be the important difference.)

But it is reproducible with my Sansa Clip+. Here the player does not disappear but can be remounted and after clicking the tick amarok crashes.
Here you need to click the tick, because otherwise it does not show any tracks. After clicking the tick first time it shows the tracks.
Ater unmounting this player, it does NOT disappear from the devices list and can be remounted. Then playing the files with kaffeine for example works, so the player is still there! But amarok does not like it anymore and decides to crash.

What about your players? All like the Samsung?

Created attachment 65946 [details]
New crash information added by DrKonqi

amarok (2.4.90) on KDE Platform 4.7.3 (4.7.3) using Qt 4.7.4

- What I was doing when the application crashed:

Pretty much looks like the one I posted some minutes ago. This is somewhat shorter and Amarok only, so I am thinking of posting it anyway as it might be more helpful than the previous. I opend the file via amarok "browse files" in left tab and opend any mp3 (it is an ogg btw, should not make a difference) on the player after remounting via widget.

My system is openSUSE 12.1 + Amarok 2.4.90 from factory.
Only some kdelibs and some soprano packages were upgraded, too. (2.7.3 or 4.7.3 now) (amarok's dependencies, only upgraded what was necessary, so most of the other stuff in my system is 4.7.2 of course... might be a reason?)

Comment 5 Myriam Schweingruber 2011-11-22 22:40:13 UTC

As explained previously I tried with external USB discs, since MSC is a USB protocol and can't reproduce this.
I can't try with anything else, my old Sansa Clip doesn't work anymore, sadly.

Comment 6 Matěj Laitl 2012-02-05 23:39:17 UTC

This should be fixed in current amarok git master by commit 76239bb9d70930b3cc6a5313ae96edfd58c39868. Please reopen the bug if you can reporoduce with currect git master.
