#40 assertion `GDK_IS_DISPLAY (display)' failed
Hi. Programs compiled with wxhaskell do not display for me at all. I am using wxhaskell 0.10.3, wxgtk 2.8.7, gtk 2.12.9, and ghc 6.8.2. I Installed wxhaskell from source, and compiling/running the sample programs provided yields the following three messages:
(process:6305): GLib-GObject-CRITICAL **: gtype.c:2248: initialization assertion failed, use IA__g_type_init() prior to this function
(process:6305): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed
(process:6305): Gdk-CRITICAL **: gdk_cursor_new_for_display: assertion `GDK_IS_DISPLAY (display)' failed
Is there anything else I can do to help troubleshoot this?

Hi there. Thanks for the report!
Unfortunately, our wxWidgets 2.8 support is working yet, so you'll have to use wxgtk 2.6.x.
Sorry for that. We're making this a top priority for wxhaskell 0.11.
I'm going to mark this as closed, but please do let us know if you run into any trouble.

All right, thank you. I guess I didn't read the documentation carefully enough. It's working fine with wxgtk-2.6.
Speaking as a user: I tried installing wxcore 0.10.5 on Ubuntu Gutsy Gibbon with wxGTK 2.8 (not 2.6 because 0.10.5 has its own dependencies), but I got the same error message as piojo_. Downgrading to both wxGTK 2.6 and wxcore 0.10.3 worked.
I am getting this same issue with wxgtku 2.8 with wxhaskell 0.11.0, even though the wiki seems to specifically state that wxhaskell 0.11 not only supports but more or less *requires* 2.8 rather than 2.6.
