Description nicolas haeberle 2008-08-09 12:59:28 UTC

Version:            (using KDE 4.1.0)
Installed from:    Unlisted Binary Package
OS:                Linux

When you access a folder on a usb drive, say with pictures on it, and you select the preview option in the dolphin toolbar, you won't be able to unmount the volume until *all* the previews are generated. This really kicks in on slow usb connections where larger previews are to be generated (say a thumbnail image of a 3 mb picture)

I think the volume should be unmountable even when not all thumbnails have been generated so on doesn't have to wait for thumbnails' creation finish just to unmount the drive.

I can confirm this issue using KDE4.3beta2. If Dolphin is open showing the content of the pen drive, i'm unable to unmount with dolphin or device manager plasmoid. If I close Dolphin, the pen drive's LED still indicates file system access (indexing?, generating previews?) but i can unmount the device via the device manager.
Dolphin should also be able to unmount the device in that situation.

Same issue using kde 4.3.0 in gentoo.

This bug is probably related to bug #207120.

I'm experiencing the same problem. Not only with USB drives, but with optical media as well. I'm using KDE 4.4.5 on Gentoo. When I open the mounted directory (containing some video files) with Dolphin, lsof will show me several kio_thumb processes using the device, and I will be unable to unmount it until kio_thumb is finished (which can take several minutes) or until I manually kill the processes.

Same Problem for me. Gentoo on stable kde 4.4

Cannot reproduce in KDE 4.7.4. Feel free to reopen this ticket if that is not the case for you.
