mcorino created an issue (wxWidgets/wxWidgets#26298)Description
@vadz While working on the integration of wxWebView in wxRuby3 I encountered a SIGSEGV issue in the the ported WebView sample on opening a link in a new (child) window.
Testing confirmed the same issue happens in the standard wxWidgets samples/webview sample.
Bug description:
When using the wxWebView functionality for opening links in a new child window the process crashes with a SEGFAULT.

vadz left a comment (wxWidgets/wxWidgets#26298)OK, this was because ready-to-show signal was unexpectedly generated twice. I'll push a fix soon and I guess it also should be applied to 3.2.
