Also add a host of debug infrastructure that was needed to find the root cause. For now it can be turned on only via defining DEBUG_SERIALIZER. In the future we might want to make it work via G_DBUS_DEBUG. In a nutshell, the added debug info looks like this Parsing blob (blob_len = 0x0084 bytes) 0000: 6c 01 00 01 3c 00 00 00 41 00 00 00 37 00 00 00 l...<...A...7... 0010: 08 01 67 00 08 61 61 79 61 7b 73 76 7d 00 00 00 ..g..aaya{sv}... 0020: 01 01 6f 00 08 00 00 00 2f 66 6f 6f 2f 62 61 72 ..o...../foo/bar 0030: 00 00 00 00 00 00 00 00 03 01 73 00 06 00 00 00 ..........s..... 0040: 4d 65 6d 62 65 72 00 00 00 00 00 00 34 00 00 00 Member......4... 0050: 03 00 00 00 63 77 64 00 01 73 00 00 23 00 00 00 ....cwd..s..#... 0060: 2f 68 6f 6d 65 2f 64 61 76 69 64 7a 2f 48 61 63 /home/davidz/Hac 0070: 6b 69 6e 67 2f 67 6c 69 62 2f 67 69 6f 2f 74 65 king/glib/gio/te 0080: 73 74 73 00 sts.
