 # These tests abort under ptest and leave the binaries in place:
-# - header-parsing-test: a g_hash_table_size() assertion in
-#   do_param_list_tests() does not hold (returns one entry instead of three)
-#   with the current glib.
+# - header-parsing-test: the /header-parsing/param-list subtest aborts as
+#   soup_header_parse_semi_param_list() returns one parameter instead of
+#   three for a header with invalid-UTF-8 extended (*=) parameters:
+#   https://gitlab.gnome.org/GNOME/libsoup/-/work_items/560
 # - logger-test (long-invalid-body-length) and http2-body-stream-test
 #   (large_data) exercise multi-GiB allocations and are killed by the OOM
 #   killer on the memory-constrained ptest machines.
