[Gtk2hs-users] Problem with Notebook and Caps-lock

[Bartosz W. <ba...@su...>]

Hi,

I have following problem I cannot fix.
In the notebook there are some packed widgets: comboBoxes, entries and 
checkBoxes. When focus is located on any of the entries, pressing caps-lock 
and num-lock causes following warning and segfault.

(ElcaGUI:24900): GLib-GObject-WARNING **: instance of invalid non-
instantiatable type `(null)'
Segmentation fault 

The number in parenthesis is of course each time different.
Alt, Ctrl, home, PF-keys etc. don't cause any warning.

Other widgets behave correct.
To the same notebook there is attached another page, static one, with 
scrolledWindow and one label packed only. Pressed caps-lock or num-lock there 
causes as well:

(ElcaGUI:26033): GLib-GObject-CRITICAL **: g_type_instance_get_private: 
assertion `instance != NULL && instance->g_class != NULL' failed

or

(ElcaGUI:26387): GLib-GObject-WARNING **: attempt to retrieve private data for 
invalid type 'GtkEntry'

Last one is strange since there is no entry widget on this page.

This problem exists on my Linux OS (gtk2hs version 0.10.0). The same program 
runs on Windows (gtk2hs version 0.10.1) without  such behaviour.

Therefore I assume there must be something either gtk2hs or OS specific.
Any help is welcome.

Best regards,
Bartek
