Can you attach a file that causes this crash?
Created attachment 49646 [details] testcase
Unfourtunatly I can't - it contains source code which doesn't belong to me. However it does seem its not related to the archive decompressed, it seems like Ark crashes if the archive has already been extracted once. If I choose "Extract, autodetect subfolder" several times on the archive attached, I get the crash.
The problem is not in Ark at all. After some investigation, I'm still uncertain whether its Strigi or KFileMetaDataWidget (and its companions) that's at fault. I've written a short test case which reproduces most of the relevant code present in KIO::RenameDialog, and I get a similar crash most of the time. Valgrind also outputs a lot of Strigi-related warnings and errors (even when the program does not crash). The more KFileMetaDataWidgets are created, the more likely it is for the crash to happen -- when only one KFileMetaDataWidget is created, it usually crashes only when I run the program with Valgrind; when two instaces are created I almost always get this crash. I'm CC'ing trueg and ppenz here as they've done most of the work on KFileMeta* stuff and can help decide if it's just Strigi that's misbehaving.
Created attachment 49656 [details] Test program that causes the same crash. This is the program I mentioned in my last comment. Just compile and run it as "kfilemetadatawidgettest /path/to/some/file" (I've tested it with banner.png from Clemens' test archive). It crashes most of the time when I create two KFileMetaDataWidget objects, as it is the case in KIO::RenameDialog.
This is one of the backtraces I got (the test case was initially called renamedialogtest): Application: renamedialogtest (renamedialogtest), signal: Segmentation fault [Current thread is 1 (Thread 0xb504e930 (LWP 32228))] Thread 3 (Thread 0xb2c37b70 (LWP 32229)): [KCrash Handler] #6 0xb5ab921b in memcmp () from /lib/libc.so.6 #7 0xb591f7c0 in MimeRule::matches (this=0x96b7668, data=0xbf32a0b8 <Address 0xbf32a0b8 out of bounds>, len=1246187464) at /home/rakuco/kde4/src/kdesupport/strigi/libstreamanalyzer/lib/eventanalyzers/mimeeventanalyzer.cpp:60 #8 0xb591f899 in Mime::matches (this=0x9851dfc, data=0x979ec80 "\310\001o\t\210\365n\t", length=1024) at /home/rakuco/kde4/src/kdesupport/strigi/libstreamanalyzer/lib/eventanalyzers/mimeeventanalyzer.cpp:84 #9 0xb592056f in Strigi::MimeEventAnalyzer::handleData (this=0x97b1160, data=0x979ec80 "\310\001o\t\210\365n\t", length=1024) at /home/rakuco/kde4/src/kdesupport/strigi/libstreamanalyzer/lib/eventanalyzers/mimeeventanalyzer.cpp:289 #10 0xb58d03c9 in Strigi::EventThroughAnalyzer::handleData (this=0x9758648, data=0x979ec80 "\310\001o\t\210\365n\t", size=1024) at /home/rakuco/kde4/src/kdesupport/strigi/libstreamanalyzer/lib/eventthroughanalyzer.cpp:71 #11 0xb580baf1 in Strigi::DataEventInputStream::read (this=0x9704388, start=@0xb2c37008, min=1024, max=1024) at /home/rakuco/kde4/src/kdesupport/strigi/libstreams/lib/dataeventinputstream.cpp:51 #12 0xb58f5981 in Strigi::StreamAnalyzerPrivate::analyze (this=0x96be830, idx=..., input=0x9704388) at /home/rakuco/kde4/src/kdesupport/strigi/libstreamanalyzer/lib/streamanalyzer.cpp:406 #13 0xb58f5641 in Strigi::StreamAnalyzer::analyze (this=0x9716ee8, idx=..., input=0xb2c370d0) at /home/rakuco/kde4/src/kdesupport/strigi/libstreamanalyzer/lib/streamanalyzer.cpp:365 #14 0xb76ab5e0 in KFileMetaInfoPrivate::init (this=0x9680e48, stream=..., url=..., mtime=1277841417, w=...) at /home/rakuco/kde4/src/kdelibs/kio/kio/kfilemetainfo.cpp:210 #15 0xb76ab891 in KFileMetaInfo (this=0xb2c371fc, path=..., w=...) at /home/rakuco/kde4/src/kdelibs/kio/kio/kfilemetainfo.cpp:237 #16 0xb77767fb in KLoadFileMetaDataThread::run (this=0x9644868) at /home/rakuco/kde4/src/kdelibs/kio/kfile/kloadfilemetadatathread.cpp:144 #17 0xb5d75f02 in QThreadPrivate::start (arg=0x9644868) at /home/rakuco/kde4/src/qt-copy/src/corelib/thread/qthread_unix.cpp:274 #18 0xb5cc5e60 in start_thread () from /lib/libpthread.so.0 #19 0xb5b1220e in clone () from /lib/libc.so.6 Thread 2 (Thread 0xb2436b70 (LWP 32230)): #0 0xb77eb7f2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 #1 0xb5b0b1f1 in select () from /lib/libc.so.6 #2 0xb5e5a95f in QProcessManager::run (this=0xb600296c) at /home/rakuco/kde4/src/qt-copy/src/corelib/io/qprocess_unix.cpp:245 #3 0xb5d75f02 in QThreadPrivate::start (arg=0xb600296c) at /home/rakuco/kde4/src/qt-copy/src/corelib/thread/qthread_unix.cpp:274 #4 0xb5cc5e60 in start_thread () from /lib/libpthread.so.0 #5 0xb5b1220e in clone () from /lib/libc.so.6 Thread 1 (Thread 0xb504e930 (LWP 32228)): #0 0xb77eb7f2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 #1 0xb5cca3fc in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #2 0xb5d7724d in QWaitConditionPrivate::wait (this=0x9557198, time=4294967295) at /home/rakuco/kde4/src/qt-copy/src/corelib/thread/qwaitcondition_unix.cpp:88 #3 0xb5d77051 in QWaitCondition::wait (this=0x9556ab8, mutex=0x9556aa0, time=4294967295) at /home/rakuco/kde4/src/qt-copy/src/corelib/thread/qwaitcondition_unix.cpp:160 #4 0xb5d76932 in QThread::wait (this=0xb600296c, time=4294967295) at /home/rakuco/kde4/src/qt-copy/src/corelib/thread/qthread_unix.cpp:660 #5 0xb5e5a722 in ~QProcessManager (this=0xb600296c, __in_chrg=<value optimized out>) at /home/rakuco/kde4/src/qt-copy/src/corelib/io/qprocess_unix.cpp:208 #6 0xb5a70ddf in ??

Thanks a lot for your investigations and your test program. We are aware about those issues and the main root cause seems to be a libdbus issue (beside some issues in Strigi analyzers)). More information is available at https://bugs.kde.org/show_bug.cgi?id=232054#c37 I'll try to focus on fixing at least the non-dbus related crashes during the next weeks.
Created attachment 49665 [details] New crash information added by DrKonqi ark (2.15) on KDE Platform 4.4.92 (KDE 4.4.92 (KDE 4.5 RC2)) using Qt 4.7.0 - What I was doing when the application crashed: I was trying to extract a rar file in Dolphin with the "Extract Archive Here" from context menu. I tried several times and I got every time the same crash until I realized that the file I wanted to extract was already in the folder. So just to check what would happend if the file wasn't there, I deleted the file and I tried again to see if I got the same crash. I didn't, it worked. -- Backtrace (Reduced): #8 0xb57a96b7 in Mime (this=0x9658c0c, __position=..., __x=...) at /build/buildd/strigi-0.7.2/src/streamanalyzer/eventanalyzers/mimeeventanalyzer.cpp:67 #9 uninitialized_copy<Mime*, Mime*> (this=0x9658c0c, __position=..., __x=...) at /usr/include/c++/4.4/bits/stl_uninitialized.h:74 #10 uninitialized_copy<Mime*, Mime*> (this=0x9658c0c, __position=..., __x=...) at /usr/include/c++/4.4/bits/stl_uninitialized.h:117 #11 __uninitialized_copy_a<Mime*, Mime*, Mime> (this=0x9658c0c, __position=..., __x=...) at /usr/include/c++/4.4/bits/stl_uninitialized.h:257 #12 __uninitialized_move_a<Mime*, Mime*, std::allocator<Mime> > (this=0x9658c0c, __position=..., __x=...) at /usr/include/c++/4.4/bits/stl_uninitialized.h:267
Hey Peter, Thanks for the update. Do you think this bug should be merged with bug 232054?
> Do you think this bug should be merged with bug 232054? Yes, although 232054 is already a container for different root causes, I think it is better to have this report linked there. *** This bug has been marked as a duplicate of bug 232054 ***
Hm, but bug 232054 is not about a crash...
> Hm, but bug 232054 is not about a crash... You're right, I've reverted the duplicate marking. I anyhow need to iterate through all tooltip/infopanel reports as soon as the issues are resolved...
I think we can close this report once again after trueg's commit 1158299, which fixed bug 232054.
*** Bug 246760 has been marked as a duplicate of this bug. ***
Looking at commit 1158299, I doubt the crash from comment #0 is fixed by it.
In this case, can you please reopen and/or test the program I've attached to this report?
I've verified KDE SC 4.5.0 with your attached test program and no crash occurs anymore. Commit 1158299 is partly involved into this: The reason for the crash of this report was that KFileMetaInfo is not reentrant and I provided a workaround in another commit that bypasses this issue. The original intention of commit 1158299 to avoid bypassing the set limit for parsing files, but Sebastian Trüg also fixed the reentrency problem of KFileMetaInfo by very nice (and necessary) cleanups of the code. However I need to do further tests with KFileMetaInfo to be 100 % sure that it is reentrant now before removing my workaround.
