Application: konsole (16.04.1) (Compiled from sources) Qt Version: 5.6.0 Frameworks Version: 5.22.0 Operating System: Linux 4.7.0-rc1-ciall x86_64 Distribution (Platform): Gentoo Packages -- Information about the crash: - What I was doing when the application crashed: I fat-fingered Ctrl+Shift+S as Ctrl+Shift+S and D. The tab closed but the save output dialogue still opened. When I chose Save in the dialogue after typing a name, this crash occurred. The crash can be reproduced every time. -- Backtrace: Application: Konsole (konsole), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond. Thank you for helping us make KDE software even better for everyone!
Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone!
Can't duplicate this on 18.08.3 with Qt 5.9.6 and KF 5.52.0. Probably fixed. (^+S immediately displays a modal that won't let me ^D under it; ^D won't let ^+S pop a save dialogue.)
