I run 64 bit Debian, and have been seeing similar problems. I get these references:
No locals.

At the time Beersmith stopped running, I noticed that Debian had just updated the libwebkitgtk components.
I think that the problem is in packaging. For most Linux packages, the dependencies are defined and confined, so that it will prevent automatic updates until it is rebuilt to match. It's likely that all the Linux distributions will one by one stop running this particular bundle. It will need to be rebuilt with more modern components to match.
Not sure if that helps. I haven't had any luck. If I try to downgrade libwebkitgtk, it would blow away lots of other software.
