Any idea what is broken? If not, it is certainly a lot easier to test with
some of the test programs in cmyth (https://github.com/cmyth/cmyth).
The ideal solution here would be to transition mvpmc to use the libcmyth
repository on github, instead of the built-in version. Then any fixes in
the library would be available to mvpmc without having to be back ported
into an older code base. However, I really have no idea how much interest
there would be in doing that, or how much use mvpmc is even getting these
days. Personally, I haven't used it in years.

I suspect that is easier said than done, although it would make perfect
sense. Since all the data structures are reference counted, any reference
to any program will keep it in memory. The only way to purge the list
first would be to clear the GUI, which could be disruptive to the user.
A more "clever" way to deal with this would be to deal with it inside
libcmyth, so it is transparent to the application. The code could
recognize that a proginfo structure is a duplicate, and increment the
reference on the original and toss the duplicate.
