Just to be sure, are you holding a reference on the web view in your Eclipse's/SWT's Browser when you create it?

What I would try is to debug the reference count of the web view (set a break point on glibc's g_object_ref()/g_object_unref() one you will know the address of the newly created web view).

No, at least I'm not aware of anything..

Just o_object_unref() it.

Try to please use https://bodhi.fedoraproject.org/updates/FEDORA-2017-368b385c04 and don't use the rawhide.

> Please advise, thank you.
