crashes in libmozjs.so

[slimer]

Hello there,

I was coding under the OS ubuntu 9.04 Desktop and compiled with gcc 4.3.3 using DialogBlocks 4.33, xulrunner 1.9.1.2. , __wxGTK__ , gtk+-2.0, toolkit wxGTK+2

I was trying to embed xulrunner with wxWebConnect in a sizer as the following code:

m_browser = new wxWebControl(itemFrame1, wxID_WEB, wxDefaultPosition, wxDefaultSize);
itemBoxSizer3->Add(m_browser, 500, wxEXPAND, 0);


whereas the itemFrame1 = this (MainFrame)
and itemBoxSizer3 has the embedded between two panels :

wxBoxSizer* itemBoxSizer3 = new wxBoxSizer(wxHORIZONTAL);
...
itemBoxSizer3->Add(itemPanel4, 140, wxALIGN_TOP|wxALL, 0);
...
m_browser = new wxWebControl(itemFrame1, wxID_WEB, wxDefaultPosition, wxDefaultSize);
itemBoxSizer3->Add(m_browser, 520, wxEXPAND, 0);
m_browser->OpenURI(_("http://www.google.com"));
...
itemBoxSizer3->Add(itemPanel5, 140, wxALIGN_TOP|wxALL, 0);


but the program crashes right after the google page comes out with the following gdb backtrace message:

Program received signal SIGSEGV, Segmentation fault.

I just googled all over and found out that it might be the gtk hardcored problem, am I right?
Or is it the other kind of bug in xulrunner?
Thanks for your help!!
