Description neal 2023-03-07 08:46:12 UTC
Application: plasmashell (5.27.2)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: FreeBSD 13.1-RELEASE-p6 amd64
Windowing System: X11
Distribution (Platform): FreeBSD Ports
DrKonqi: 5.27.2 [KCrashBackend]

-- Information about the crash:
When I first login having previously accessed files over nfs, but my nfs server is not currently available, plasmashell will continually crash.
This raises the question: why on earth is plasmashell try to access filesystems that I have not currently asked it to do?

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

If something crashed, we need a backtrace of it so we can figure out what's going on. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl.

Can you please attach one using the `coredumpctl` command-line program, as detailed in the above documentation? Thanks!

Unfortunately I don't seem to have the coredumpctl utility. Maybe it's a Linux thing. I did however manage to capture the following from the KDE crash handler (it never finished submitting the original report, which may be why the information was missing):

resultmodel: guard model in threaded resource cleanup

this previously was subject to a race condition between ResultModel
destruction and the file access finishing. When the file access took
long enough the Model would have been deleted leading to a crash.

Instead weakly point to the model via the QObject such that we can then
check if still exists by the time we want to call into it
Related: bug 458121
Fixes PLASMA-WORKSPACE-YZ
