https://bugs.kde.org/show_bug.cgi?id=378445 --- Comment #16 from r...@alum.mit.edu --- Happened again in charge_state_changed. This *may* have been at the time my laptop reached full charge but I have no logs. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=378445 --- Comment #13 from r...@alum.mit.edu --- That's not likely what happened here; this most often happens overnight when I had shut the laptop's lid, and it's not right after I shut it either (I have my lid set to lock when shut, not suspend). I wasn't

[Powerdevil] [Bug 378445] kscreenlocker_greet occasionally freezes in malloc in signal handler

https://bugs.kde.org/show_bug.cgi?id=378445 --- Comment #12 from Martin Gräßlin --- Assuming the signal handler is the reason the steps to reproduce are: Let screen lock through idle timeout and during grace period lock the screen through shortcut -- You are receiving this

https://bugs.kde.org/show_bug.cgi?id=378445 --- Comment #10 from r...@alum.mit.edu --- Note that frame 5 is a signal handler, so it's hardly surprising that frame 4 and frame 7 are unrelated. I don't know this code, but it sure looks to me like something (in the second trace, isValidBusName; in

https://bugs.kde.org/show_bug.cgi?id=378445 --- Comment #7 from r...@alum.mit.edu --- Still happens with kscreenlocker (and powerdevil) 5.9.4. It's rare, so I can't reproduce it reliably. And I don't have the debuginfo packages -- my normal source for KDE packages doesn't have the debuginfo
