gtk_widget_modify_style: assertion failure under wxpython 2.6

[tim.henderson]

Hello

I am not sure if this is the right list to post this on, so if there
is a better one please point me towards it.

I recently upgrade my laptop from winXP to Kubuntu 6.10 and my
application that I am developing broke. However the error I am getting
does not seem to be very helpful, and doesn't stop the application
from running in every version of the app.

My program can be found at secure-data.sourceforge.net

here is my error for version (1.5.1.2):

(python:12254): Gtk-CRITICAL **: gtk_widget_modify_style: assertion
`GTK_IS_WIDGET (widget)' failed

It actually still runs even though it gives me this error. however for
latest version of my program I get this error plus a segmentation
fault as well and thus the application stops. This leads me to believe
this is problem with the under lying c++ not the python wrapper

here is my error for version(1.6 b3):

(python:12268): Gtk-CRITICAL **: gtk_widget_modify_style: assertion
`GTK_IS_WIDGET (widget)' failed
(170, 350)

(python:12268): Gtk-CRITICAL **: gtk_widget_modify_style: assertion
`GTK_IS_WIDGET (widget)' failed
Segmentation fault

notice I get the Gtk error twice instead of one as well as the
segmentation fault.

Has anybody run into problem before. I did not run it similar posts by
googling through several groups. If anybody has any insight i would
much appreciate it, as i have gotten nowhere in my debugging so far.

Not this program runs fine under winXP, i have yet to test it the
latest under MacOS X yet.

Thank you for reading my message
