This have been reported a couple of times. It is a bug in the QuickAccess widget, which is not developed by KDE nor supported in this bugtracker: Thread 1 (Thread 0x7f3b3c204750 (LWP 10900)): [KCrash Handler] #5 QUrl (this=0x7fff455ee360, other=...) at io/qurl.cpp:3936 #6 0x00007f3b3b84afc9 in KUrl::KUrl(KUrl const&) () from /usr/lib/libkdecore.so.5 #7 0x00007f3b3ae51ec0 in KFileItem::url() const () from /usr/lib/libkio.so.5 #8 0x00007f3b1edddcde in ?? () from /usr/lib/kde4/plasma_applet_quickaccess.so You can report it to its maintainer (in the kde-look page?) Regards i see two bugs here. the first one causes quick access to go wonky, the second causes plasma to crash because of it. certainly you don't think plasma should be crashable through a widget. as stated above, "i believe the bug to lie in the widget, though i also believe plasma should handle this better." About the second issue, check: http://forum.kde.org/viewtopic.php?f=15&t=83712 http://www.freehackers.org/thomas/2009/11/10/wonders-from-a-kde-fan-and-developer-about-some-kde-design-choices/ (and its comments) and bug 199754 Regards BTW, I'm not a Plasma dev, just a bug triager. |
Application that crashed: plasma-desktop Version of the application: 0.3 KDE Version: 4.3.2 (KDE 4.3.2) Qt Version: 4.5.2 Operating System: Linux 2.6.31-14-generic x86_64 Distribution: Ubuntu 9.10 What I was doing when the application crashed: this happens every single time i click on the quick access widget, set to my home dir, and it cannot find the directory. the file/folder listing has nothing in it, yet it functions as its supposed to: hover over the current directory line, you can see 'Open:' slide in as always, you can change sorting options, but as soon as you click away to close it, plasma crashes. i believe the bug to lie in the widget, though i also believe plasma should handle this better. -- Backtrace: Application: Plasma Workspace (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0x7f3b3c204750 (LWP 10900))] Thread 3 (Thread 0x7f3b1ba7d910 (LWP 10903)): #0 0x00007f3b389c35a9 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #1 0x00007f3b3bc494fb in QWaitConditionPrivate::wait (this=<value optimized out>, mutex=0xd23358, time=18446744073709551615) at thread/qwaitcondition_unix.cpp:87 #2 QWaitCondition::wait (this=<value optimized out>, mutex=0xd23358, time=18446744073709551615) at thread/qwaitcondition_unix.cpp:159 #3 0x00007f3b3808078c in QHostInfoAgent::run (this=0xd23340) at kernel/qhostinfo.cpp:260 #4 0x00007f3b3bc48445 in QThreadPrivate::start (arg=0xd23340) at thread/qthread_unix.cpp:188 #5 0x00007f3b389bea04 in start_thread () from /lib/libpthread.so.0 #6 0x00007f3b3959e7bd in clone () from /lib/libc.so.6 #7 0x0000000000000000 in ??
