Bug#1098501: haskell-gi-vte :FTBFS:build failed ( Could not load module ‘GI.GdkPixbuf.Objects.Pixbuf’)

Dear haskell-gi-vte maintainer,

The package haskell-gi-vte build failed on riscv64. The crucial buildd log below:

```

GI/Vte/Callbacks.hs:98:1: error:
    Could not load module ‘GI.GdkPixbuf.Objects.Pixbuf’
    It is a member of the hidden package ‘gi-gdkpixbuf-2.0.32’.
    Perhaps you need to add ‘gi-gdkpixbuf’ to the build-depends in your .cabal file.
    Use -v (or `:set -v` in ghci) to see a list of the files searched for.

The full buildd log is here:

My solution to this issue:

The error occurs because the module "GI.GdkPixbuf.Objects.Pixbuf" cannot be loaded on the riscv64 architecture, as it belongs to the hidden package "gi-gdkpixbuf-2.0.32". My solution is to explicitly add "gi-gdkpixbuf-2.0.32" to the build-depends list in gi-vte.cabal.I have tested that locally, and it works well.The debpatch is in the attachment. Please let me know whether this solution can be accepted.
