Oops, I spoke too soon; not careful enough. Reinstalling gtk3 via
cabal install does *not* get the repaired version; I am still seeing
the assertion error. I don't pretend to understand how all this
installation machinery works, so I mention this in case you thought
what you did would make the fix available via cabal. If not, when do
you expect it to be available?

WatchGuard Dimension instantly turns raw network data into actionable
security intelligence. It gives you real-time visual feedback on key
security issues and trends. Skip the complicated setup - simply import
a virtual appliance and go from zero to informed in seconds.
