Comment (by quozl):

 Thanks for the logs; but they have nothing indicative.

 Fedora 26 is using Sugar 0.110 as released with one patch from master.
 There are 30 other patches in master not included, but none of them are in
 the screenshot or global hotkey features.

 I can't afford a download of those ISOs at this time, but as you've got
 them already please do some more tests;

 * try the frame activation of screenshot, see test case 2 below; this
 should narrow the problem to either global hotkey response ''or'' journal
 datastore writing,

 * try the `Alt` key in the home view activity ring; it should cause
 activities with journal entries to lose colour; this proves whether Sugar
 is properly receiving the key event,

 * in {{{/usr/share/sugar/extensions/globalkey/screenshot.py}}} in the
 {{{handle_key_press}}} function, change

 {{{
 def handle_key_press(key):
     take_screenshot()
 }}}

 to

 {{{
 import sys

 def handle_key_press(key):
     print >>sys.stderr, repr(take_screenshot())
 }}}

 and then restart Sugar without rebooting, try taking a screenshot using
 `Alt+1`, and look at `shell.log` for the response; this should prove the
 hotkey is responded to.

 ----

 Test case 1; press `F5` to display Journal, then `Alt+1` and a 'Screenshot
 of "Journal"' entry with image viewer icon should be shown.

 Test case 2; press `F5` to display Journal, then `F6` to display frame,
 then right-click on the display icon, and select "Take a screenshot", and
 a 'Screenshot of ' entry should be shown.
