Comment # 3 on bug 964989 from Steffen Winterfeldt

This is probably the same as bug 875369. The config parser didn't like
incomplete files (particularly non-matching parentheses).

The bug is fixed in 13.2 and later (in package perl-Bootloader-0.813).

13.1 is out of support meanwhile but if you want you can install some newer
perl-Bootloader releases from software.opensuse.org.
