Sentry Crash Report:

Description Tony 2016-10-19 20:11:39 UTC 
Application: plasmashell (5.8.90)

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.4.0-43-generic x86_64
Distribution: KDE neon Developer Edition

-- Information about the crash:
As the title says. It does not happen all the time you need to keep switching and hitting apply for it to trigger a couple of times.

I know there is a bug with the "Configure Desktop" window, it silently closes after you've changed the view type and hit apply, never got a desktop crash before.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 4 Christoph Feck 2017-06-28 18:37:18 UTC 
Backtrace from comment #1 is completely unrelated to the originally reported crash.

Duplicates from comment #2 and comment #3 are actually duplicates of the wrongly added backtrace.

Marco, how should I handle this mess?
Comment 5 Christoph Feck 2017-06-28 18:38:00 UTC 
Tony, please report your issue as a new ticket, unless you are experienced with comparing backtraces.

Which? The initial one or 1st comment or a completely new bug report.
Comment 7 Tony 2017-06-29 00:11:41 UTC 
...sorry ok will do report issues as new, have cero experience comparing backreaces.
Comment 8 David Edmundson 2017-08-13 20:28:48 UTC 
the original crash is now fixed in Qt5.9.2

#2 and #3 traces are dupes of 381630 which we can track there.
