[GNC] 5.13 Crash When Creating Transaction Between Currencies

[John Ralls]

Somebody else reported this on Thursday and I can reproduce it. It happens after the price lookup and seems to be problem with a stale signal handler firing after the Transfer Dialog has been destroyed. That’s consistent with all of those “has no handler with id…” errors.

I think I have a fix but I’m having a linking problem in my build environment just now so I haven’t been able to test it yet.

Regards,
John Ralls
