--- Comment #5 from Alberto Garcia <berto at igalia.com> ---
This is the actual command called by g-ir-scanner:

./liferea --introspect-dump=/tmp/tmp-introspectw0lgbi6d/functions.txt,/tmp/tmp-introspectw0lgbi6d/dump.xml

And this is the backtrace:

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