Package: ksnapshot
Version: 4:4.4.4-1+b1
Severity: normal

If alt-tab is pressed after dragging the image from KSnapshot (with left mouse
button still pressed), KSnapshot crashes. This behaviour can be
reproduced, I attached a backtrace with libqt4-dbg installed.

This bug renders the drag-n-drop functionality of KSnapshot partly
unusable since one can only drag the image to windows that are on the
screen at the time (so no alt-tab-ing is needed).

Dear ksnapshot user,

ksnapshot has not been developed upstream for many years already, and
Spectacle (available in the kde-spectacle package) replaced it upstream
and also in Debian, starting from Debian 9 (Stretch).

Since ksnapshot was removed from Debian more than 4 years ago, it is
time to close all the open bugs for it. Spectacle, even if it does
something similar to what ksnapshot did, is a totally different
application started from scratch (and thus not sharing anything
code-wise with ksnapshot); because of this, there is no point in moving
all the ksnapshot bugs to Spectacle.

Most probably you have been using Spectacle already for a few years;
we recommend to report bugs and feature requests for it directly to
the upstream bug tracker system: https://bugs.kde.org/, product
"Spectacle".

Thank you again for you report,
-- 
Pino Toscano
