I'm using WebKitGtk+ with my own JHBuild setting:
https://github.com/tanty/jhbuild-epiphany/tree/wkgtk-devel

MiniBrowser from WebKit 2.12.5

The compilation was done with CMake args:

"-DPORT=GTK -DCMAKE_BUILD_TYPE=Debug -DDEVELOPER_MODE=ON -DCMAKE_C_FLAGS_DEBUG=-g1 -DCMAKE_CXX_FLAGS_DEBUG=-g1"

When visiting several pages, eventually, WebKitWebProcess crashes.

This bug is not reproducible in a predictable way.

---

The action that triggered the crash was deattaching a tab from a window to create a new 1 tab window.
