Bug#802589: plasma-workspace: krunner dies with SIGSEGV
Package: plasma-workspace Version: 4:5.4.3-1 Followup-For: Bug #802589 Hi, I'm running into a similar issue with 5.4.3 version (unfortunately I can't afford to pull 5.5 version from experimental at the moment). The common thing is that a quick input (on my machine: anything quicker than around one character per second) causes krunner to crash, but some other symptoms are different (e.g. the backtrace). Here's a backtrace from a couple of weeks ago: https://gist.github.com/emkael/b8d6ea9632d457e34dc8 Usually it goes like this: 1. first use of krunner after booting up/launching user session crashes out on "quick" input 2. after that, krunner restarts/recovers and one of two following things occur: 3a. it crashes once again, even on a carefully slow input and gives up 3b. it does not crash, but launches applications with / as a current directory, instead of user's home directory 4. either way, once put out of its misery and relaunched manually (`killall krunner; krunner &` or similar), it starts to behave normally -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (650, 'testing'), (600, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 4.3.0-1-amd64 (SMP w/6 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages plasma-workspace depends on: ii dbus-x111.10.6-1 ii frameworkintegration5.16.0-1 ii gdb 7.10-1+b1 ii kactivities 5.16.0-1 ii kde-cli-tools 4:5.4.3-1 ii kded5 5.16.0-1 ii kinit 5.16.0-1 ii kio 5.16.0-1 ii libc6 2.21-7 ii libcln6 1.3.4-1 ii libdbusmenu-qt5-2 0.9.3+15.10.20150604-1 ii libgcc1 1:5.3.1-8 ii libgps223.15-2 ii libice6 2:1.0.9-1+b1 ii libkf5activities5 5.16.0-1 ii libkf5auth5 5.16.0-1 ii libkf5baloo55.16.0-1 ii libkf5bookmarks55.16.0-1 ii libkf5completion5 5.16.0-1 ii libkf5configcore5 5.16.0-1 ii libkf5configgui55.16.0-1 ii libkf5configwidgets55.16.0-1 ii libkf5coreaddons5 5.16.0-1 ii libkf5crash55.16.0-1 ii libkf5dbusaddons5 5.16.0-1 ii libkf5declarative5 5.16.0-1 ii libkf5globalaccel-bin 5.16.0-1 ii libkf5globalaccel5 5.16.0-1 ii libkf5guiaddons55.16.0-1 ii libkf5i18n5 5.16.0-1 ii libkf5iconthemes5 5.16.0-1 ii libkf5idletime5 5.16.0-1 ii libkf5itemviews55.16.0-1 ii libkf5jobwidgets5 5.16.0-1 ii libkf5js5 5.16.0-1 ii libkf5jsembed5 5.16.0-1 ii libkf5kdelibs4support5 5.16.0-1 ii libkf5kiocore5 5.16.0-1 ii libkf5kiofilewidgets5 5.16.0-1 ii libkf5kiowidgets5 5.16.0-1 ii libkf5networkmanagerqt6 5.16.0-1 ii libkf5newstuff5 5.16.0-1 ii libkf5notifications55.16.0-1 ii libkf5notifyconfig5 5.16.0-1 ii libkf5package5 5.16.0-1 ii libkf5plasma5 5.16.0-1 ii libkf5plasmaquick5 5.16.0-1 ii libkf5quickaddons5 5.16.0-1 ii libkf5runner5 5.16.0-1 ii libkf5screen6 4:5.4.3-1 ii libkf5service-bin 5.16.0-1 ii libkf5service5 5.16.0-1 ii libkf5solid55.16.0-1 ii libkf5su5 5.16.0-1 ii libkf5texteditor5 5.16.0-1 ii libkf5textwidgets5 5.16.0-1 ii libkf5wallet-bin5.16.0-1 ii libkf5wallet5 5.16.0-1 ii libkf5waylandclient54:5.4.3-1 ii libkf5waylandserver54:5.4.3-1 ii libkf5webkit5 5.16.0-1 ii libkf5widgetsaddons55.16.0-1 ii libkf5windowsystem5 5.16.0-1 ii libkf5xmlgui5 5.16.0-1 ii libkf5xmlrpcclient5 5.16.0-1 ii libksgrd7 4:5.4.3-1 ii libkworkspace5-54:5.4.3-1 ii libpam0g1.1.8-3.2 ii libphonon4qt5-4 4:4.8.3-2 ii libplasma-geolocation-interface54:5.4.3-1 ii libprocesscore7 4:5.4.3-1 ii libprocessui7 4:5.4.3-1 ii

Bug#802589: plasma-workspace: krunner dies with SIGSEGV
Package: plasma-workspace Version: 4:5.3.2-4 Severity: normal Pressing Alt-F2 to summon krunner, and then typing "loc" (for localc) quickly crashes krunner every time. Perhaps that search string won't help reproducing, because your document history is different or so - OTOH the information might be enough. GDB says: Program received signal SIGSEGV, Segmentation fault.
