Hey! Just checked line 119 in kget runner... QDBusConnection::sessionBus().interface()->isServiceRegistered(KGET_DBUS_SERVICE) Anyone has a clue why that could crash? Maybe Qt bug? Lukas (In reply to comment #1) > Hey! > Just checked line 119 in kget runner... > QDBusConnection::sessionBus().interface()->isServiceRegistered(KGET_DBUS_SERVICE) > > Anyone has a clue why that could crash? Maybe Qt bug? QDBusConnection::sessionBus() seems not to be thread-safe (see bug 208921) *** Bug 227667 has been marked as a duplicate of this bug. *** Bug 222234 is related to this too... From bug 230038: -- Information about the crash: KRunner tends to crash often, it happens while quickly typing in it. It is allso slow to react, for example, typing gg: and some text behind it krunner often lags by 10 seconds before executing commands. The exact command that i was typing when it crashed was name of the window "dol close" dol stands for dolphin and as i started typing close krunner crashed From bug 228658: -- Information about the crash: Krunner is running in task oriented view. When trying to type this command "kdesu kate /boot/grub/menu.lst" krunner would stop after "kdesu kate /boot/grub/menu". After klicking with the mouse into the address bar it worked. When I tried to type in the command a second time after I had started the application it worked fine. Same with the command which caused the crash. Crash on the first time I've typed the command, it worked on the second time. *** Bug 230038 has been marked as a duplicate of this bug. *** (note: bug 228658 (mentioned in the last comment) is a different issue) *** Bug 233906 has been marked as a duplicate of this bug. *** *** Bug 222234 has been marked as a duplicate of this bug. *** Created attachment 43562 [details]

KRunner crashed while using the Calculator plugin and after pressing [BackSpase]. ('=336*2+150+18' -> '=336*2+15')

krunner (0.1) on KDE Platform 4.5.3 (KDE 4.5.3) using Qt 4.6.3
It seems the bug is still there in 4.5.3.
Using dbus 1.2.24
Could reproduce a crash twice in a row when entering a mathematical calculation like:
=48*1986*8476
See backtrace:

I don't see a reference to KGet in that bt. Does it also happen if you deactivate the KGet runner? (In reply to comment #17) > I don't see a reference to KGet in that bt. Does it also happen if you > deactivate the KGet runner? Have you taken a look at the attached BT or only the reduced one (that's what DrKonqi does now). In the attached BT are some references to KGet, I just don't know, whether they're actual worthy or just meaningless in the backtrace path. [Comment from a bug triager] Backtrace on comment 16 seems to be a bit different to the backtraces on this report. It is likely to be related to the dbus threading issues fixed since libdbus 1.4.0 Bug 259713 is from KDE SC 4.4.4: -- Information about the crash: I observed that the MPlayer plug-in embedded in Ark preview is unable to play a song so I told it to copy the URL of the song. The URL was sort of /tmp/kde-krzysztof/arkSrkmv7//kahvi297a_speaK-I_love_it_here.ogg (notice the double slash); there is no such file. I pasted it to the run dialogue and tried to get to the enclosing folder. The run dialogue auto-prepended smb: (because of the double slash?) and eventually crashed. *** Bug 259713 has been marked as a duplicate of this bug. *** Created attachment 58198 [details]
