flatpak-builder 1.4.4-2 freezes and is unkillable with latest update. prior version worked fine.

Just raising the flag as a possible issue, I have a flatpak yml that went from functioning to failing every time with the latest update. I've rolled back my system and my build environment runs a different distro so I'm fairly indifferent to debugging this. just wanted to let you know.

Description:

the following module causes flatpak-builder to freeze and become entirely unresponsive at the end of it compilation. can't even be killed with kill -s 9. I suspect its related to the fuse patch.

Additional info:

package version: 1.4.4-2

    - name: libass
      buildsystem: autotools
      config-opts:
        - --disable-static
        - --enable-asm
        - --enable-harfbuzz
        - --enable-fontconfig
      sources:
        - type: git
          url: https://github.com/libass/libass.git
          tag: 0.17.3
          commit: e46aedea0a0d17da4c4ef49d84b94a7994664ab5

Steps to reproduce:

build the the module above. i suspect mpv's flatpak might trigger this.
