Comment 2 for bug 352077

I think fundydan's approach linked here is what I was talking about:

If you still require me to write the patch myself I'll do it; I'm at work and can't do it right now.

I suspect multiple instances being accidentally triggered are what's behind the number of backend crashes I've been experiencing on and off over the last few months.

Hi Andrew:

I think this is a good idea, if you can write a patch for the mythfrontend
startup script, that would be even better. It's in sh, and located at
/usr/bin/mythfrontend . We'd be glad to integrate it then.
