Hi all,

Martin sent out an email a few days ago letting you know that we're
trying to use the issue tracker
(http://gnuradio.org/redmine/projects/gnuradio/issues) to report and
fix bugs in a more timely manner.

As part of that process I'm going to send out an occasional email to
the list, to remind everyone that the issue tracker exists, and bring
outstanding bugs to peoples attention.  If anyone feels like having a
go at fixing a bug then assign yourself to it in the issue tracker, so
that we don't get multiple people working on it at the same time.

Bugs that need some attention are:

The 'Persistence' option that comes with most wxgui-sinks rarely
works, and always produces crashes if it doesn't.

I think we could detect this feature and change the label text to "crash
me" if not present.

My preference for this one is to simply disable the feature altogether until someone does a top-to-bottom re-write of our use of wxGUI/PyGl that manages, as if by magic, to successfully skirt around all the bugs in OpenGL. OpenGL is a farking minefield of "oh sorry, that feature is now a hardware dependent feature, and you don't have this weeks hardware, so,
  well, SEGFAULT".

Does the relatively-simple 2D rendering done by GNu Radio graphs really require OpenGL? I"m not an expert, by any means, but those types of graphs (simple line graphs, and even the waterfall) were the sorts of things we were doing over 100Mbit
  connections to an X-terminal 20 years ago.  No OpenGL.
