Bug#906213: gnome-sound-recorder: conditional catch clauses are incompatible with gjs 1.53.90+

[Simon McVittie]

Package: gnome-sound-recorder
Version: 3.28.1-1
Severity: important
Tags: upstream buster sid
Control: block 906016 by -1

gjs 1.53.90+ switches its Javascript implementation from mozjs52 to
mozjs60, a newer Mozilla Spidermonkey release which drops some
Mozilla-proprietary extensions. A gjs maintainer has developed a tool,
<https://gitlab.gnome.org/ptomato/moz60tool>, which can be used to check
for most of the problem cases.

When I ran that tool against gnome-sound-recorder I got this warning:

gnome-sound-recorder/src/listview.js:114:42: Conditional catch clause used.
  WRONG:   catch (e if e.code === 23) {...}
  CORRECT: catch (e) { if (e.code === 23) {...} }

This has probably been fixed upstream for GNOME 3.30. The GNOME team is
in the process of uploading GNOME 3.30 libraries to experimental.

gjs will need to have a Breaks against unfixed gnome-sound-recorder versions.
