Follow-up: With latest darcs version, showing revision 0.11.1 this time, this error does not occur any longer. However, wxhaskell is still not working as now programs fail with:
(process:3353): GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.16.6/gobject/gtype.c:2248: initialization assertion failed, use IA__g_type_init() prior to this function (process:3353): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed (process:3353): Gdk-CRITICAL **: gdk_cursor_new_for_display: assertion `GDK_IS_DISPLAY (display)' failed This happens for the example I mentioned in my previous e-mail but also for the examples included with wxhaskell (BoxedCombinator etc). Any help with this? The parameters stayed the same as in my previous e-mail (Ubuntu 8.04, wxwidgets/wxgtk 2.8.7 ubuntu version), I even tried updating to wxwidgets 2.8.9, but to no avail, same error. I build wxhaskell with "cabal" install, followed by the cd wx en usual build process if that may be of any help.
