On nixpkgs master/staging we have 2.32 - that includes this patch.
https://nvd.nist.gov/vuln/detail/CVE-2018-7738 claims 2.32-rc1 fixes
this and upstream master hasn't changed umount completion except for
this patch, so it has to be it. /cc #38994.

(cherry picked from commit 8994bf5)

When opening `shutter` it adds an indicator icon to the status bar.
However this doesn't happen (and an ugly default icon will be used) if
`shutter` can't find the `hicolor-icon-theme`. In such a case a warning
like this can be found in `stderr`:

```
Gtk-WARNING **: Could not find the icon 'image-png'. The 'hicolor' theme
was not found either, perhaps you need to install it.
```

As I don't think that we should force users to install this theme
globally and several other packages including `tor-browser`, `gparted`
or `clawsmail` add `hicolor-icon-theme` to their closure this seems to
be a fair measure.

…port

However, none of the exporters I tried actually _worked_, but now
shutter at least returns an error to the user (pop-up UI element)
instead of silently hanging and only leaving messages on stdout/stderr
about the missing deps.

AFAICS, this changes the failure of Screenshot->Export functionality
from a packaging bug to an application bug (upstream).

This update was made based on information from https://repology.org/metapackage/libcue/versions.

These checks were done:

- built on NixOS
- Warning: no binary found that responded to help or version flags. (This warning appears even if the package isn't expected to have binaries.)
- found 2.2.1 with grep in /nix/store/lqppvr2arq1jmmdil3519c2y7hhm0vq3-libcue-2.2.1

Security update. master has already 2.9.0

In some cases, this seems to save a lot (>40%) of space.
