It reproduces with 4:5.8.7-1. I was planning on testing it on an Intel
video laptop I have at home, but didn't get around to it over the
weekend. I'll forward it upstream once I've tested there.

(note: a friend found this on his Stretch box, and asked me to try it on 
my testing/unstable box where it happens as well. So this bug affects 
stable.)


With widgets unlocked: Right click desktop -> add panel -> default panel 
Nothing appears to happen. After a moment (and possibly some clicking on 
the desktop), plasmashell segfaults.


I installed the dbgsym packages and ran it under GDB, obtaining a hug 
(19M!) backtrace, as it has over 76,000 frames—appears like infinite 
recursion. Though I'm somewhat confused why there are different frames 
on both ends, unless that's the crash report error handler trying to 
work...



Thankfully, xz managed to bring it down to 139K. Attached.



Both of us are using the nVidia proprietary drivers, if that matters.


I can't reproduce the issue here with an intel card, so it might be that the 
issue is related to the nvidia drivers. I'm not really sure, can you test if 
the issue is still reproducible for you with 4:5.8.7-1, currently in unstable?


(we have already requested approval for 4:5.8.7-1+deb9u1 for it to enter in 
stretch)


If the problem persist with 4:5.8.7-1, could you please forward this issue 
upstream, reporting the issue in: https://bugs.kde.org ? If you do so, please 
also send us an update with the upstream url bug.


Happy hacking,
