Do you have XDG_CONFIG_HOME, XDG_DATA_HOME, or XDG_CACHE_HOME set in
your environment?

There is a pledge for $XDG_CACHE_HOME/dconf which should expand to
~/.cache/dconf unless you have XDG_CACHE_HOME set to something else.

When pledge() fails, it calls mozilla::ipc::FatalError which
triggers MOZ_CRASH_UNSAFE, which calls abort(), so these crashes are
expected.
