-- Information about the crash:
There was no further user-action necessary to provoke this error. I simply tried to start KMail when KMail crashes. I hope, the code, created by the Crash-Handler is more helpful.

The crash can be reproduced every time.

PimCommon::AbstractGenericPluginInterface::setParentWidget (this=this@entry=0x0, parent=0x5555560ef3d0) at /usr/include/c++/15.1.1/bits/unique_ptr.h:193
193           pointer    _M_ptr() const noexcept { return std::get<0>(_M_t); }

I attached the gdb output.
