** Description changed:
+ [Impact]
+
+ Making screenshot of the current window might result in mate-screenshot
+ crashing.
+
+ The fix for this issue is provided in the debdiffs attached to the
+ report.
+
+ Would be nice to have the fix backported to Zesty and Artful, as the
+ issue breaks one of the common features that users expect to work
+ always.
+
+ [Test Case]
+
+ Use Alt-PrintScreen (or "mate-screenshot -w" from the terminal) to grab
+ the current window.
+
+ As stated in the original description, this should be tried on PowerPC
+ machines to reproduce the bug reliably. In this case, mate-screenshot
+ should crash. Intel/AMD machines may or may not be affected.
+
+ [Regression Potential]
+
+ The fix is achieved by removing some unneeded code from mate-screenshot.
+ The code was obtaining window title from the current window, but that
+ title wasn't used by any other parts of code afterwards. The only effect
+ of removing that code is fixing the crash, as it happened exactly in
+ that part. Therefore, there's no place for regressions here.
+
+ [Original Description]
+
mate-screenshot always crashes when doing a 'grab the current
window'-screenshot. Doing a screenshot of the whole desktop works.
Tested on Zestys daily iso on a PowerBook G4 5,6.
