Application that crashed: plasma-desktop Version of the application: 0.3 KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1)) Qt Version: 4.5.1 Operating System: Linux 2.6.28-12-generic i686 Distribution: Ubuntu 9.04 What I was doing when the application crashed: To recreate the crash: Just open the Desktop Settings dialog and then click the Browse button to browse for wallpaper on your hard drive. Plasma hangs and after a few minutes you have to close the dialog. The browse dialog never shows up. Even after closing, plasma is still not responsive. After a few minutes, I used kquitapp to quit plasma, and thats when the crash notification came up. I am running this on Kubuntu 9.04 with KDE 4.3 Beta1. -- Backtrace: Application: Plasma Workspace (plasma-desktop), signal: Segmentation fault [Current thread is 0 (LWP 3619)] Thread 4 (Thread 0xa7d21b90 (LWP 3627)): #0 0xb7fe7430 in __kernel_vsyscall () #1 0xb50b80e5 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0xb63082ed in pthread_cond_wait () from /lib/tls/i686/cmov/libc.so.6 #3 0xb64ec5b2 in QWaitCondition::wait (this=0x9b7d968, mutex=0x9b7d964, time=4294967295) at thread/qwaitcondition_unix.cpp:87 #4 0xb794aae2 in QHostInfoAgent::run (this=0x9b7d958) at kernel/qhostinfo.cpp:260 #5 0xb64eb56e in QThreadPrivate::start (arg=0x9b7d958) at thread/qthread_unix.cpp:189 #6 0xb50b44ff in start_thread () from /lib/tls/i686/cmov/libpthread.so.0 #7 0xb62f949e in clone () from /lib/tls/i686/cmov/libc.so.6 Thread 3 (Thread 0xa3bb5b90 (LWP 3628)): #0 0xb4e6e0ac in clock_gettime () from /lib/tls/i686/cmov/librt.so.1 #1 0xb660ce2b in QTimerInfoList::getTime (this=0x9c9463c, t=@0x9c94660) at kernel/qeventdispatcher_unix.cpp:339 #2 0xb660d001 in QTimerInfoList::updateCurrentTime (this=0x9c9463c) at kernel/qeventdispatcher_unix.cpp:297 #3 0xb660b2f3 in timerSourceCheck (source=0x9c94608) at kernel/qeventdispatcher_glib.cpp:156 #4 0xb4eb56f6 in g_main_context_check () from /usr/lib/libglib-2.0.so.0 #5 0xb4eb5fdd in ??

this looks like a bug in the filewidget, not the image plugin.
*** Bug 196136 has been marked as a duplicate of this bug. ***
Is this still happening with a recent KDE build? Thanks

This may be related or it may be unrelated. I'll post another bug report if unrelated. Using KDE 4.3.0 and Arch Linux, changing a wallpaper 'Picture' will sometimes result in the 'Picture' setting becoming blank - no wallpaper selection appears whatsoever. If 'Apply' is clicked thereafter, the background comes up as if no option were selected and the background color is the only thing that appears. Upon changing the background image once again, the wallpaper changer begins working as expected. There may be some relation here considering the crash and the location of the crash, atleast in my mind anyway. Nonetheless, I'll await further instruction.
This bug is, as i found, due to duplication of libs withing archlinux when moving from kdemod to kde in the distribution. To solve this bug, remove all of kde and then look for any libs that belong to KDE and delete them.

For those of us using strict KDE from the repos within Arch Linux, however, this suggestion tends to go out the window. ;) Personally speaking, I've never used KDEmod and have no intention of using it.
I believe yours is a different bug, although similar to this one. I would start a different bug report otherwise it might get burried in this one. The backtrace on the original poster points to KFileDialog bug through plasma which is the one due to duplicate libs. Does it crash when you do kquitapp plasma-desktop?

hi, i reported the same issue today as bug 209844, but apart from a lot of closed dupes there us not real solution to this. i don't have any mixed libraries (gentoo, kde from trunk) and so its not invalid for me, please reopen at least one bug to trace this. how can on help with debugging?
*** Bug 211823 has been marked as a duplicate of this bug. ***
I see the bug resolved as invalid, can I ask why? It's not really a bug? Is there a workaround to fix it?
This is marked as INVALID because of comment 7; however... the issue has appeared on another systems too. But I can't be sure it isn't a downstream issue (on distributions) anyways...
Reopening... Updated backtrace from bug 212716: --- Thread 1 (Thread 0xb6065700 (LWP 3062)): [KCrash Handler] #6 0xb4b0868b in KFileWidget (this=0x9273fa8, _startDir=..., parent=0xa85dcae0) at ../../kfile/kfilewidget.cpp:598 #7 0xa3b453fb in KFileModule::createFileWidget (this=0x8939b20, startDir=..., parent=0xa85dcae0) at ../../kfile/kfilemodule.cpp:36 #8 0xb79f529f in KFileDialog (this=0xa85dcae0, startDir=..., filter=..., parent=0xa854c3f0, customWidget=0x0) at ../../kio/kfile/kfiledialog.cpp:238 #9 0xa974708e in Image::showFileDialog (this=0xa854c4a8) at ../../../../plasma/wallpapers/image/image.cpp:469 #10 0xa974a873 in Image::qt_metacall (this=0xa854c4a8, _c=QMetaObject::InvokeMetaMethod, _id=11, _a=0xbfa7a00c) at ./image.moc:106
From the same bug report: What I was doing when the application crashed: I changed the folders name where my wallpaper is located but I forgot to change the path in the desktop background settings. When I opened the dialog for changing the wallpaper and selected the "browse"-option the whole stuff crashed pretty bad...

#9 0xa974708e in Image::showFileDialog (this=0xa854c4a8) at ../../../../plasma/wallpapers/image/image.cpp:469 that line is "{" in the 4.3 branch. so, once again, we have something that's been patched. http://websvn.kde.org/tags/KDE/4.3.2/kdebase/workspace/plasma/wallpapers/image/image.cpp?view=markup i assume it's the new KFileDialog on line 471, in which case this is certainly a KFileDialog issue not a plasma issue. looking at the code in KFileDialog, i'd not be surprised if it's a similar issue to the one already reported: a broken installation in some way. the reporter is using debian testing; perhaps a package update will fix it "magically" for them. in any case, information on whether it's repeatable or not, whether it happens only when opening the file dialog to a url that doesn't exist, whether it happens in other apps as well, etc would be useful.
please reopen this bug if you can reproduce it with kde 4.4 (trunk)
