Bug description:
[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.
