[RESOLVED] Problem with kioslave5: Looping Error

[wonder]

The thing is, I don't know how or why, but now this is happening to me. When I open Dolphin and it has to recreate a thumbnail, a lot of kioslave5 error windows pop up, and honestly, I don't know what's causing it.

I took a snapshot, then rolled back to Kubuntu 24.04.3 (from August 2025), updated with the available updates, restarted, and I'm still getting the error.

I've been searching but haven't found anything that fixes it...

Any ideas?

Thanks in advance.

Edit: I'm adding that Gwenview isn't opening any images for me.

Edit 2:
The info for developers is:

Application: kioslave5 (kioslave5), signal: Segmentation fault

Edit 3:
Fixed with this:

sudo apt install libexiv2-27=0.27.6-1build1

I downgraded that package, just to see if it was the problem.
It did indeed fix it; after restarting, it's working.
Now it indicates there's an update, so for now I'll freeze it on this version...

[skyfishgoo]

sudo apt install libexiv2-27=0.27.6-1build1


is the workaround until the guys at kubuntu sort out their version conflict

you will see a notice that a security update is pending... leave it like that for now

if you have updates set to automatic you can turn that off or you can hold the package, but i do not recommend holding it unless this drags out.

That's right, that's what I've done to fix it, but I've also "frozen" this version so the update doesn't appear. In a few days, I'll unfreeze it to see if there are any updates on this.

set a reminder so you don't forget... but i'll try to post back here if there is any progress

[wonder]

Thanks, yes, after how hard it was to spot the problem today, I don't think I'll forget.

Anyway, that's the plan: a reminder and a weekly review.

Gweniew stopped working today, and so have some other image viewers that I tried. Rolling back also did not work. Sometimes a segmentation error pops up. Seems to be related to a faulty update?? I also got the repetitive kioslave error windows when I was messing with Dolphin and Mirage (temporary substitute for Gwenview). Waiting and hoping for an update.

You try this?:

[skyfishgoo]

the patch is out with the 0.27.6-1ubuntu0.3 version

it is safe to let that update roll in

quick work by the (k)ubuntu team.

The Kubuntu update this morning fixed it. That was quick! All good.

That's right, I just unfroze the old version, installed the new one, and there are no problems; it works perfectly.
They were quick.

Thanks for the heads-up.
