Comment 6 for bug 35916

So, looking at it, this seems relevant:

>>>Thread 1 (Thread -1231623968 (LWP 28806)):
>>>#0 0xb7482101 in g_utf8_validate () from /usr/lib/libglib-2.0.so.0
>>>#1 0xb744bf18 in strdup_len () from /usr/lib/libglib-2.0.so.0
>>>#2 0xb744c44e in g_filename_from_utf8 () from /usr/lib/libglib-2.0.so.0
>>>#3 0xb66dd299 in get_attachment_list ()

I can tell you, the filename of the attachment has been different every time, and has not contained any special characters. For instance, this time I used 'new file' on my desktop, containing only the word "blah".
