It looks as if this is because NS_WEBBROWSER_CONTRACTID ("@mozilla.org/embedding/browser/nsWebBrowser;1") isn't in the component registry. Is there some change to the way I need to initialize gtkmozembed? Reproducible: Always Steps to Reproduce: 1. Install FC6 2. Download and run democracyplayer as described at https://develop.participatoryculture.org/projects/democracy/wiki/GTKX11BuildDocs Actual Results: App crashes. After debugging, have traced problem to do_CreateInstance.
Maybe you should report this to the democracy guys, too?
I am one of the democracy guys. I'm trying to figure out how to change democracy to fix it.
Looks like this is the same bug as reported here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=205499
It is the same thing, I think. It's explored further here, I think. I've explored it some more. On FC6, we fixed it by calling set_comp_path. However, with newer gtks like on ubuntu or gentoo, a very similar crash occurs unless you set LD_LIBRARY_PATH to the mozilla path.
i'll gladly r+ the patch to add the null check, please post it, or wait for me to do all the other work i have to do to catch up. but the null check won't solve your problem. gecko embedding requirements include someone telling gecko where to find the libraries they want used. classically this is handled by run-mozilla.sh.
What are you trying to embed, and what linkage strategy are you using?
