-- Information about the crash:
Spectacle wasn't running before pressing Meta+Print. I'm trying to capture QEMU SDL window. After pressing Meta+Print, Spectacle crashed instead of capturing a screenshot. The QEMU guest is running KDE as well.

The crash can be reproduced every time.

-- Backtrace:
Application: Spectacle 截图工具 (spectacle), signal: Segmentation fault

Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

Could you please install debug symbols for Qt and Spectacle, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks again!
