** Description changed:

+ [Impact]
+ 
+ On Hirsute/Impish, update-notifier can crash when attempting to run
+ hooks.
+ 
+ [Test Case]
+ 
+ Create a file 'bug'
+ 
+ 'Name: bug
+ Priority: Low
+ Command: "/bin/true"
+ DisplayIf: /bin/true
+ Description: update notifier bug'
+ 
+ and copy it to /var/lib/update-notifier/user.d
+ 
+ [Where problems could occur]
+ 
+ This is not the most absolute minimal version of this fix.
+ If the minimal version of the fix is desired, I can provide that, which 
should be a +2/-2 diff.
+ The fix changeset includes other glib usage improvements which sound good 
from a maintainability perspective and may even close other yet unknown bugs 
but add their own risk of regressions if said maintainability was not done 
correctly.
+ 
+ [Original Bug Report Description]
+ 
  The issue is new using https://code.launchpad.net/~dbungert/update-
  notifier/+git/update-notifier/+merge/397367 , the previous revision
  didn't have the issue

- One comment in addition on the change there, was the env split + iterate over 
pathdirs basically a re-implementation of 
https://developer.gnome.org/glib/stable/glib-Miscellaneous-Utility-Functions.html#g-find-program-in-path
 ? If there is particular reason to do that I would recommend just using the 
glib function instead (which might also fix the issue as a side effect, I 
didn't check)
