Crash upon activation when installed on Fedora

I was able to install `geany-zencoding` from source on my new Fedora-based box. (I've installed quite easily before on Ubuntu, but new to Fedora)

After installation, I get the following error message (revealed from `geany -v`)

```
ImportError: No module named zencoding
Segmentation fault
```

When run via gdb, I got the following backtrace from the time of the segfault:

```
ImportError: No module named zencoding

Program received signal SIGSEGV, Segmentation fault.

Unfortunately, I'm not either a C or Python developer, so I'm at a loss when it comes to further debugging.

Bắt đầu bằng cách tái hiện lỗi kích hoạt với `geany -v` và kiểm tra `plugin.c` tại `plugin_init`, dòng 519, cùng `zen-controller.c` tại `zen_controller_set_active_profile`, dòng 238. Theo dõi cách lần import `zencoding` thất bại để lại trạng thái kích hoạt trước lệnh gọi profile. Hoàn tất khi bản cài đặt Fedora không còn bị segmentation fault khi import thất bại và lỗi được báo cáo một cách an toàn.
