Is this crash reproducible? Not really. It happens randomly maybe once a week or two. Hm, the backtrace is not very telling either. Please make sure to provide a new backtrace next time that happens to you. Well, it took more than a week or two for it to happen again. Here's a new backtrace, as you requested. I somehow have the feeling this is more likely to happen when things are not fully loaded yet and have to be fetched from disk, like just after starting KDE, after resuming from hibernation on a laptop, or after there has been considerable memory pressure. Just a hunch; that may be a completely false lead too. My original report was from a crash on a desktop machine, while this one is from a laptop and happened just after resuming from hibernated state (with caches dropped at hibernation). Judging from the backtrace I'd guess it's the same cause as my original report, most likely heap corruption. Hmm, perhaps there's a way to arrange krunner to always run with env MALLOC_CHECK_=2 or some similar thing? That way I guess this could be caught earlier and possibly with a better backtrace. $ krunner --version Qt: 4.8.2 KDE Development Platform: 4.8.4 (4.8.4) Run Command Interface: 0.1 ------------------------------------------------------------ Application: Run Command Interface (krunner), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". __lll_lock_wait_private () at ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S:97 [Current thread is 1 (Thread 0x7fa6d4342780 (LWP 4546))] Thread 11 (Thread 0x7fa6cced4700 (LWP 4549)): #0 __lll_lock_wait_private () at ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S:97 #1 0x00007fa6e7e9c6b8 in _L_lock_9627 () from /lib/x86_64-linux-gnu/libc.so.6 #2 0x00007fa6e7e9aaa1 in *__GI___libc_free (mem=0x7fa6e81a4e60) at malloc.c:3736 #3 0x00007fa6e4944b13 in socketNotifierSourceCheck (source=0xef3200) at kernel/qeventdispatcher_glib.cpp:92 #4 0x00007fa6dd3fa13b in g_main_context_check () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 #5 0x00007fa6dd3fa5c2 in ??

I found this in my .xsession-errors log:
krunner(15605)/kdecore (trader) KTraderParse_error: Parsing "exist Exec and ('gg:kde taskbar won't open' =~ Name)" gave: syntax error
Seems it has troubles with the single-quote in there.
Fixed with Plasma 5. |
