This is reproducible on a fresh Manjaro as well but only when running a frozen binary (not when running from sources). The segfault occurs somewhere inside libpthread according to GDB. A naïve Google search like "cx_freeze segfault pthread" reveals marcelotduarte/cx_Freeze#1132 which suggests that updating cx_Freeze might help.

This was solved, the binary is now available at https://files.zubax.com/products/com.zubax.kucher/v1.1.0.beta/linux-x86_64/
