I'm sorry. I think it means that an instruction in memory address
"0x100098a9" attempted to write to address "0x00448950", which is a
segfault probably. The error message does not say the latter
explicitly, only that "written" could not be performed (the wording
sounds equally strange in german).

Yes, I did. I quoted the excerpt to corner the error down.
