Bug#859100: webkit2gtk: webkit2gtk loads system-installed extensions by default

Package: libwebkit2gtk-4.0-37
Version: 2.14.5-2
Severity: normal
File: webkit2gtk

It appears that when/if a java or flash plugin is installed from
another debian package, webkit2gtk tries to load it, even when
setting a custom, local, webextensions directory as documented in

This is really a cause of many troubles, for example, i had installed
and some webkitgtk client i use suddenly started crashing - but this
auto-loading behavior does not seem to be documented.
