Common segfault after attaching in plasma-welcome

[olib14]

Often times when attaching GammaRay to a running instance of KDE Plasma's Welcome Centre (plasma-welcome), the application will immediately crash. This is the case for the application both shipped in 6.2.5 and built from source.

GammaRay: 3.1.0

stdout:

<Application output omitted>
gammaray_probe_attach()
Resending server address...
Segmentation fault (core dumped)

Backtrace:

Program terminated with signal SIGSEGV, Segmentation fault.
