#169 geeqie crashes on invalid filename encoding

GUI (73)

Geeqie 1.0 core dumps when opening a directory with non-utf8 filenames. It generates traceback like that:

It seems to happen because g_utf8_collate_key() always expects a valid UTF-8. In the attached diff I check if the file name if a valid UTF-8 string, if it's not convert it using g_filename_display_name(). It fixes a problem for me.

    I am afraid this patch causes a leak and maybe other problems. For a correct fix we have to review FileData structure and separate file access and display purpose variables.

    For now I have commited a simpler fix which should prevent the crash above, git 27bec4237fa34883854d8c83ce1484fcc0aef165
