Summary: querying memory/physical/buffer crashes ksystemstats
on FreeBSD
Classification: Frameworks and Libraries
Product: ksystemstats
Version: 6.2.4
Platform: FreeBSD Ports
OS: FreeBSD
Status: REPORTED
Severity: normal
Priority: NOR
Component: General

SUMMARY
querying memory/physical/buffer crashes ksystemstats on FreeBSD
STEPS TO REPRODUCE
1. run "kstatsviewer memory/physical/buffer"
OBSERVED RESULT
ksystemstats crashes
EXPECTED RESULT
Return the amount of memory used for buffer (FreeBSD shows that in top).
SOFTWARE/OS VERSIONS
FreeBSD/KDE Plasma: FreeBSD 15-CURRENT
KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.9.0
Qt Version: 6.7.3
ADDITIONAL INFORMATION
I think dbus library called abort(): I see this when it crashed
QDBusMarshaller: type 'ulong' (35) is not registered with D-Bus. Use
qDBusRegisterMetaType to register it
dbus[48596]: Array or variant type requires that type variant be written, but
end_struct was written.
The overall signature expected here was 'a(sv)' and we are on byte 3 of that
signature.
I'll try to debug it. Here's the stack trace:
