Screenshot showing what K3b wants to remove

I'm also having the exact same problem.

Created attachment 94174 [details]
screenshot of similar dialog; k3b-2.0.80+git on plasma5

Similar screenshot; should mv this to -> confirmed

This is with

rpm -qa | egrep -i "k3b-2|plasma5-desktop-"
 k3b-2.0.80+git20150209.2250-1.5.x86_64
 plasma5-desktop-5.3.91git~20150821T120904~da2274c-135.1.x86_64

Same happens here on OpenSUSE Tumbleweed with k3b-2.0.80+git20150209.2250-1.10.x86_64 (didnt upgrade recently).
Should we provide some additional information?

Can't I edit a comment? 
However, to check if the device is in use k3b calls 

lsof -Fpc dev->blockDeviceName()

e.g. 

lsof -Fpc /dev/sr0

In my case, that indeed outputs all of the processes it shows in the dialog (k3blsofwrapperdialog).
The problem seems to be that lsof outputs pipes with these parameters, which you see when you omit the field selection parameter (-Fpc) :

$ lsof -w /dev/sr0

Does someone know by heart how to omit pipes and sockets with lsof? Otherwise I will try to investigate tomorrow and maybe provide a patch.

Hi Andre, I can only speak for myself and I have to say I do not know how to do what you suggest.

Thank you for keeping us udated,

Hugh

I am getting quite a lot of this as well after the latest update to k3b 17.12.2, KF5 5.43, I am trying to rip my CDs to audio files. 

Running openSUSE tumbleweed, kernel 4.15.5.

Before the update (kernel 14.4, KF5 5.40 or something) I was also getting this, but with much fewer applications, so "check again" would work. Currently check again does help much (the same applications are listed).

Also, every application with a tray icon is also listed (e.g. viber).

I have the same problem, device in user

openSUSE Tumbleweed

on openSUSE Tumbleweed, reverting to lsof-4.89-6.3.x86_64 solves this problem for me.  

lsof-4.90-1.1.x86_64
lsof-4.90-50.3.x86_64

both cause k3b to fail for me

lsof-4.91-1.1

solves this for me
