Apparently this is a general problem of Sonnet::Dialog, which cannot 
handle empty buffers. I was able to reproduce the crash outside of 
Subtitle Composer in an isolated example by passing an empty buffer to 
Sonnet::Dialog.

Sonnet::Dialog's specification doesn't exclude empty buffers, so I 
consider this a bug in Sonnet. But even so, it might be good to work 
around this problem in Subtitle Composer, too. Even the KDE people 
themselves (the creators of Sonnet) apply that kind of workaround in 
their applications (e.g. in Kate [1] [2]).

I've created a patch working around the problem by skipping empty 
entries (they don't have to be checked anyway). It's in the package's 
git repository, waiting to be uploaded.
