simple-scan and Xsane crash shortly after start with SIGABRT in bugchk-free

When I start simple-scan, xsane or scan2pdf the programs stop after shortly after starting.
The simple-scan log in the cache folder:

There is a huge crash file in /var/crash:
_usr_bin_simple_scan.0.crash. May I post all?

Maybe more interesting is the crash file _usr_lib_colord-sane.113.crash:
