Description Sebastian Dröge (slomo) 2007-08-03 21:54:37 UTC 
Hi,
since gtk 2.11.6 several applications segfault after an assertion failure in gtk_widget_ensure_style:

(audacity:27621): Gtk-CRITICAL **: gtk_widget_ensure_style: assertion `GTK_IS_WIDGET (widget)' failed

The backtrace is:

+ Trace 152650

  • #0 ??
    from /usr/lib/libwx_gtk2u_core-2.6.so.0
  • #1 wxSystemSettingsNative::GetColour
    from /usr/lib/libwx_gtk2u_core-2.6.so.0
  • #2 ??
  • #3 ??
  • #4 wxAppConsole::CallOnInit
  • #5 wxEntry
    from /usr/lib/libwx_baseu-2.6.so.0
  • #6 wxEntry
    from /usr/lib/libwx_baseu-2.6.so.0
  • #7 ??
  • #8 __libc_start_main
    from /lib/tls/i686/cmov/libc.so.6
  • #9 ?? 

Downgrading to gtk 2.11.5 makes it work without problems again.

This problem also happens with acroread for example, see http://www.adobeforums.com/cgi-bin/webx?128@@.3bc4895e

If you need a better backtrace I can try to get one with debugging symbols tomorrow.

Bye

The assertion failure itself yields the following backtrace:

Not sure how I can get debug symbols for wxgtk on Ubuntu unfortunately, the debug package doesn't do it for some reason.
Comment 2 Sebastian Dröge (slomo) 2007-08-04 07:46:21 UTC 
Ah, this comes from revision 18418: GtkTooltips->tip_window is used in wxgtk for some reason (although it's marked private) and in that revision it's use in Gtk was stopped and tip_window is always NULL.

Not a Gtk bug then I guess... unless you care for users of private fields?
