Bug Description

When a file was opened in `vlc` and played back and the playback finished, moving that file in a file manager (reproduced in `dolphin` and `nautilus`) takes up to several seconds (during which the file manager freezes) while the move occurs instantly when it is opened with `kaffeine` (after the playback finished - and as well when it is played back). The doesn't occur irregularily when the file is moved during playback. The issue occurs on btrfs filesytems only.

The issue really only occurs with `vlc` and there're no issues regarding file moving or freezes of the file manager(s).

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to . Please test the latest v3.19 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I can confirm the filmed behavior for the start and it is applicable to opening a video when another is playing as well. The issue occurs randomly in my case, though.

I'm thinking this is related to the desktop session manager (I posted a GDB backtrace in the VLC thread above).

On Linux 3.19.1 in Ubuntu 14.10 amd64 files which have been played with `vlc` 2.2.0-pre2 cause `gdm` to hang for > 30 minutes (after that time I killed `nautilus` in another tty with `pkill nautilus`) if these failes are dragged (dropping isn't possible due to hang and necessity to kill `nautilus`).
