Title: Fix segfault in thumbnailer (Uninitialized GError) 

hwp-thumbnailer가 다음과 같은 에러를 내면서 죽습니다.
```
(process:18150): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Error opening file: No such file or directory

Program received signal SIGSEGV, Segmentation fault.
```

GError를 NULL로 초기화하니 이런 현상이 사라졌습니다
