Description Frank Griffin 2012-08-29 13:21:11 CEST

In current cauldron, k3b hangs when you eject a DVD.

If you fire up k3b with a DVD in the drive, use Tools->Copy Medium to copy the DVD to an ISO image file, and Start, the operation works perfectly.  If you then eject the DVD to mount another, the GUI freezes at the eject.  The Copy dialog window showing the successful copy operation will not dismiss.

If you dismiss the Copy window before the eject, it closes.  If you then eject, the main GUI freezes.

If you double-click on Window-Close, you'll get the usual "not responding" dialog, and selecting "Close" does close KDE.

Basically, to process multiple DVDs with k3b, you have to premount a DVD, run k3b, kill k3b, mount another, etc.

Running k3b from the command line, the last message before the freeze is the MEDIA CHANGE event message.

Here's the STDOUT/STDERR from a run in a terminal.  In this case, I successfully closed the Copy dialog prior to hitting EJECT:

Comment 2 Nic Baxter 2015-03-29 03:10:29 CEST

I can't reproduce in 5Beta3. Works. Assume it was fixed in the last 30 months so closed.
