Dear Maintainer,

Thread 1 "systemsettings" received signal SIGSEGV, Segmentation fault.

Dear Maintainer,
I still can reproduce this with current Trixie/testing [1] [2].
The crash seems to happen because for some reason the member m_tags
contains an invalid pointer 0x1 [3].
With rr-debugger I could record such a crash and reverse execute to
where m_tags got overwritten with this 0x1 [4].
Unfortunately I still cannot tell the exact reason,
because the crash no longer happens with a locally rebuilt
package libkaccounts2.
Therefore, might this be an ABI break?
And could be solved by a binNMU of libkaccounts2?
Kind regards,
Bernhard
