| Subject: [PATCH] Empty values are not valid GParamSpec |
| |
| The validate() vfunc for GParamSpecParam returns FALSE for empty GValue, |
| which means the is_valid() vfunc should do the same. |
| |
| This avoids a segfault when calling g_param_value_is_valid() on a |
| GParamSpecParam. |
| |
| Fixes: #2770 |
