[grapefruit] [Gtk2hs-users] missing texts

[Michael Dever]

Hi,

Upon doing a re-install, and a fresh installation of gtk2hs 0.10, everything
is working again. Properly... no hidden text. So it must be something to do
with an update to Gtk, maybe.

In my update list, it says I have to install 3 different Gtk2+ engine
updates. Maybe one of this has an affect?

Cheers,
Michael
