[wx 2.8.7, GTK 2, gcc 4.1.2] assertion failures in AUI

Wed Feb 13 05:27:09 PST 2008

Hi folks,

with wxGTK 2.8.7 on Debian 4.0/x86_x64, I always get failed assertions
when undocking or re-docking an AUI pane from/to a window, and when
trying to rearrange the tab panes in an AUI notebook. AFAIR, this didn't
happen in the version I used before (I think it was 2.8.6). The
following is from the auidemo that comes with wxWidgets:

[Debug] 02:20:57 PM: ./src/gtk/frame.cpp(330): assert "(m_wxwindow !=
NULL)" failed in GtkOnSize(): invalid frame

Here's the backtrace:

Program received signal SIGTRAP, Trace/breakpoint trap.

My apologies if the bug is already known. If this isn't the correct list
to send bug reports to, please let me know where I should send this.

TIA. mkb.
