Application: kate (3.4.0) KDE Platform Version: 4.4.00 (KDE 4.4.0) Qt Version: 4.6.2 Operating System: Linux 2.6.32.9-70.fc12.i686 i686 Distribution: "Fedora release 12 (Constantine)" -- Information about the crash: I edited some files through sftp in kate and these files were saved in a session. Then I closed kate and reopened it and chose to open that session again. Kate crashed. Reopening kate and choosing that session (containing only sftp files) crashes kate everytime. Opening other sessions works fine, but when switching from them to the sftp one, kate crashes, everytime. I use ssh key (enabled by ssh-add), so no password is required for opening the files through sftp. The crash can be reproduced every time. -- Backtrace: Application: Kate (kate), signal: Segmentation fault [Current thread is 1 (Thread 0xb76e97a0 (LWP 3911))] Thread 2 (Thread 0xb5f61b70 (LWP 3912)): #0 0x00c61416 in __kernel_vsyscall () #1 0x00418c45 in pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/i386/i486/pthread_cond_wait.S:122 #2 0x07782567 in QTWTF::TCMalloc_PageHeap::scavengerThread (this=0x78546c0) at ../3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:2304 #3 0x077825b2 in QTWTF::TCMalloc_PageHeap::runScavengerThread (context=0x78546c0) at ../3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:1438 #4 0x00414ab5 in start_thread (arg=<value optimized out>) at pthread_create.c:297 #5 0x0033fdce in clone () at ../sysdeps/unix/sysv/linux/i386/clone.S:130 Thread 1 (Thread 0xb76e97a0 (LWP 3911)): [KCrash Handler] #6 isValid (this=0x9c5c980, proxyIndex=...) at /usr/include/QtCore/qabstractitemmodel.h:77 #7 KateViewDocumentProxyModel::mapToSource (this=0x9c5c980, proxyIndex=...) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateviewdocumentproxymodel.cpp:346 #8 0x03ed84eb in KateViewDocumentProxyModel::sort (this=0x9c5c980) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateviewdocumentproxymodel.cpp:620 #9 0x03ed8f18 in KateViewDocumentProxyModel::opened (this=0x9c5c980, index=...) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateviewdocumentproxymodel.cpp:216 #10 0x03eadb16 in KateMainWindow::slotWindowActivated (this=0x9c3d340) at /usr/src/debug/kdesdk-4.4.0/kate/app/katemainwindow.cpp:572 #11 0x03eb3285 in KateMainWindow::qt_metacall (this=0x9c3d340, _c=InvokeMetaMethod, _id=<value optimized out>, _a=0xbf9e983c) at /usr/src/debug/kdesdk-4.4.0/i686-redhat-linux-gnu/kate/app/katemainwindow.moc:181 #12 0x0476a5db in QMetaObject::metacall (object=0x9c3d340, cl=InvokeMetaMethod, idx=59, argv=0xbf9e983c) at kernel/qmetaobject.cpp:237 #13 0x047794af in QMetaObject::activate (sender=0x9c4c810, m=0x3ef5584, local_signal_index=1, argv=0x0) at kernel/qobject.cpp:3293 #14 0x03eb63c8 in KateViewManager::viewChanged (this=0x9c4c810) at /usr/src/debug/kdesdk-4.4.0/i686-redhat-linux-gnu/kate/app/kateviewmanager.moc:164 #15 0x03eb87d1 in KateViewManager::activateView (this=0x9c4c810, view=0x9cfc9b8) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateviewmanager.cpp:462 #16 0x03eb9692 in KateViewManager::createView (this=0x9c4c810, doc=<value optimized out>) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateviewmanager.cpp:301 #17 0x03ebbc93 in KateViewSpace::restoreConfig (this=0x9c544b8, viewMan=0x9c4c810, config=0x9954da0, groupname=...) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateviewspace.cpp:252 #18 0x03eb72b7 in KateViewManager::restoreSplitter (this=0x9c4c810, configBase=0x9954da0, group=..., parent=0x9c4c810, viewConfGrp=...) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateviewmanager.cpp:795 #19 0x03eba6ea in KateViewManager::restoreViewConfiguration (this=0x9c4c810, config=...) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateviewmanager.cpp:701 #20 0x03eb13d1 in KateMainWindow::KateMainWindow (this=0x9c3d340, sconfig=0x9954da0, sgroup=..., __in_chrg=<value optimized out>, __vtt_parm=<value optimized out>) at /usr/src/debug/kdesdk-4.4.0/kate/app/katemainwindow.cpp:208 #21 0x03e988c3 in KateApp::newMainWindow (this=0xbf9ea354, sconfig_=0x9954da0, sgroup_=...) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateapp.cpp:389 #22 0x03ec5c60 in KateSessionManager::activateSession (this=0x993ca58, session=..., closeLast=false, saveLast=false, loadNew=true) at /usr/src/debug/kdesdk-4.4.0/kate/app/katesession.cpp:341 #23 0x03ecae66 in KateSessionManager::chooseSession (this=0x993ca58) at /usr/src/debug/kdesdk-4.4.0/kate/app/katesession.cpp:484 #24 0x03e9a266 in KateApp::startupKate (this=0xbf9ea354) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateapp.cpp:182 #25 0x03e9a658 in KateApp::initKate (this=0xbf9ea354) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateapp.cpp:135 #26 0x03e9a8aa in KateApp::KateApp (this=0xbf9ea354, args=0x9815e10) at /usr/src/debug/kdesdk-4.4.0/kate/app/kateapp.cpp:72 #27 0x00afb475 in kdemain (argc=2, argv=0xbf9ea9f4) at /usr/src/debug/kdesdk-4.4.0/kate/app/katemain.cpp:373 #28 0x0804864c in main (argc=2, argv=0xbf9ea9f4) at /usr/src/debug/kdesdk-4.4.0/i686-redhat-linux-gnu/kate/app/kate_dummy.cpp:3 Reported using DrKonqi

might be fixed in gitorious with this commit (see bug# 213014): http://gitorious.org/kate/kate/commit/f6702b275e3f50f4cbe6dbf8755db36fef5b7319 Can you build Kate from gitorious and try again? http://gitorious.org/kate/pages/Building%20Kate

is this related to 203774? might be fixed, please try with current git version of kate and tell us whether the problem persists.
yes, fixed for kde >= 4.4.4. @Jaak: if you "git pull" and recompile with `make install` the crash should be gone. *** This bug has been marked as a duplicate of bug 203774 ***
This is fixed for me in the newest git version! Thank you very much! This makes work so much easier! Note: Could build kate easiliy with instructions found here http://dhaumann.blogspot.com/2010/04/quick-compiling-kate-in-stable-kde.html
@Johannes: Better use http://gitorious.org/kate/pages/Building%20Kate. This is identical to your link, but contains a little fix: It's debugfull instead of fulldebug :)
