I have a feeling what happens but can you install debug symbols for plasma-integration to see where inside it tries to do winId()
(In reply to Kai Uwe Broulik from comment #1) > I have a feeling what happens but can you install debug symbols for > plasma-integration to see where inside it tries to do winId() Is this useful?

Manjaro packages (being based on Arch) do not provide debug symbols, unlike RPM or DEB packages.
I can confirm the crash here, thanks.
The QtCurve settings module seems to delete the window and confuses Qt in the process. Even if I fix this very crash, I then end up crashing in other places where it tries to access the old window which is now dangling. I have never seen this crash in any other place, so I consider this a client bug, re-assigning to QtCurve.
Is the master version ok? I cannot reproduce this somehow....

(In reply to Yichao Yu from comment #6) > Is the master version ok? I cannot reproduce this somehow.... To reproduce, you need to turn on the global menu added in Plasma 5.9. Current master *is* affected.

OK, I think the bug is really in plasma-integration. I've reported it as bug 379719 (https://bugs.kde.org/show_bug.cgi?id=379719).

Got pushed an update containing QTCurve fiels from openSUSE today. Still having the same crash. Attached a backtrace but it looks similar, if not identical, to the one I posted last time. Duplicate #382433

I am testing Leap 15 Build 115.1 using Plasma 5.11.95 and crash still happening.
Update When I remove the menubar from the desktop qtcurve no longer crashes.
Technically, this is indeed bug 379719, but not duplicating, because QtCurve is probably the only user of MDI windows with menus. It would be possible to workaround the Qt bug in QtCurve kcm but ommitting the menubar in the preview window.
For now, this should disable the crash and we can access the .qtcurve files. Yes?

Having the same issue with Arch. Latest everything, hmm
@Yichao Yu What does Yichao have to say about this bug? He is the maintainer of Qtcurve.

This doesn't seem to be fixed? Still crashing on 1.9.1 with global menu enabled

The fix is in Plasma, so you do not have the fix. If it crashes when global menu is disabled, you are seeing a different crash. Please create a new ticket with the backtrace.

I don't have the fix yet on downstream, using kubuntu v18.04 lts as a test, upgrading it off and on. Making a live cd image thing out of it. And a side note, qtcurve crashes ubiquity installer, the qt ver. The gtk3 ver runs fine. That's without the app title bar menu thing, it just crashes. Another issue is colors keep changing for gtk apps, I don't know what the deal is.. I can simply open the app, half a dozen times, and maybe 10% of those times I'll get the right color scheme. I have no clue what is going on with that. Sometimes losing it's transparency too. Really screwy, I have no idea if it's qtcurve yet, the gtk2 part of it, or kde it's self, or just my screwing up on the cfg files. For example: plasma-org.kde.plasma.desktop-appletsrc, I've preset it 4-5 times, notta, real pain. I could have a mix of settings conflicting who knows. This is on my custom live image, I can go back to scratch if I have to. I've got so many other issues with it right now though, too many crashes and lockups. So called soft crashes, hardlock the virtual machine.. Anyways.... I gotta figure out how to get the latest build's of kde5 on kubuntu 18.04. Prob is I got 4 custom widgets I modded, I don't wanna keep havign to re-write them. I'm gonna have to figure out the metadata stuff, rename, and use the stock ones as dep's. That way I can upgrade and not worry about it. Then find the repo, if there is one..., I think there is, but not 100% on that lol. Something like that anyways. Sorry for the offtopic. I figured I'de give a heads up, been seeing a ton of comments on the bug report in my email so I figured I'de stop by, give a heads up on what I've found so far. I'de check with the Ubiquity installer as a heads up, something going on there, likely belongs in a completely different bug report tbh.
