+Subject: [PATCH] flatpak-proxy: Fix D-Bus disconnection with overly long
+ object paths
+
+According to the D-Bus specifications:
+https://dbus.freedesktop.org/doc/dbus-specification.html#id-1.4.4
+For the STRING and OBJECT_PATH types, [the data length] is encoded in 4
+bytes (a UINT32).
+
+But the code was trying to parse the 32-bit integer as an 8-bit one,
+meaning that, as was the case with object paths created by the dLeyna
+project, a 259-byte long string would be parsed like a 3-byte long
+one.
+
+Fixes: 004b7b2ca0e9 ("Parse dbus headers") in flatpak
