File as-glib-PR359.patch of Package appstream-glib

Subject: [PATCH] Fix crash with invalid children of <ul/>

It segfaulted when building the error message as data_c->name was invalid.
data_c was a valid tag, so only the data_c->tag union member was active.
Fix the crash by calling the proper function instead and add a test case.
