Plasma Apps not opening quickly -- possible apparmor related

Summary

When I open windows or any dialogue box it takes a few minutes to open, for example if I open Kolourpaint and save as, the application freezes, this is the error in terminal:

"Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

If I open Gwenview, it appears on the taskbar but does not open. In terminal I get the following:

QPainter::setOpacity: Painter not active
QPainter::end: Painter not active, aborted
kf.solid.backends.udisks2: Failed enumerating UDisks2 objects: "org.freedesktop.DBus.Error.NoReply"
"Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

If I open Dolphin I get this error:

 "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

 "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

I tried to fix broken packages but it affect it, when I update I get the following error:

This is still happening for me, searching more it seems to be related to udisks2, see https://github.com/storaged-project/udisks/issues/1139

[TraceyC77]

This is probably not related to that issue. The issue in udisks was fixed in 2.10.1, their latest release, which is what we have in the stable repo. Also libblockdev in the repo is 3.2.0, which is the latest upstream release.

I don't see the same errors opening Dolphin or Gwenview, they both open immediately. (Plasma system on unstable repo)

The errors about apparmor and cbm are more likely relevant

[TraceyC77]

The udisk errors are likely unrelated to this crash, but for completeness those are related to this upstream bug

@pmaccarron , Is this problem still happening for you on an up to date system?

[pmaccarron]

Hi @TraceyC77, the slowness to open those apps has stopped thankfully, I was still getting the AppArmor error on one machine recently but not my other. I intended to check last night but forgot, however, the main issue is resolved. Thanks!
