It only happens if the "show file preview" option is enabled in Dolphin. I also have this issue (on ArchLinux). The following is the report generated by Dr.Konqi while running version 5.106. kioslave5 crashes when opening a folder containing my music library in Dolphin, or when opening my home folder in Kates "Open File" dialog. Interestingly it is not crashing when opening my home folder in Dolphin. File previews are enabled (and it doesn't crash with them disabled). The file in question in both cases is an ext4 filesystem, on an internal SSD drive for my home and on a normal HDD for my music library. I tried to convince gdb to give me the name of the failing file by following https://community.kde.org/Guidelines_and_HOWTOs/Debugging/Debugging_IOSlaves and attaching to the thumbnail kio process but I've not had any luck as the types are incomplete (I think some TagLib stuff was optimized out too much or the ArchLinux debug information aren't complete enough). ``` Application: kioslave5 (kioslave5), signal: Segmentation fault Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>} [KCrash Handler] #6 0x00007f557419e514 in () at /usr/lib/libtag.so.1 #7 0x00007f557419f436 in TagLib::MP4::Atoms::find(char const*, char const*, char const*, char const*) () at /usr/lib/libtag.so.1 #8 0x00007f557419f4e2 in TagLib::MP4::File::hasMP4Tag() const () at /usr/lib/libtag.so.1 #9 0x00007f55837940ca in parseMP4Tag<TagLib::MP4::File> (file=...) at /usr/src/debug/kio-extras/kio-extras-23.04.1/thumbnail/audiocreator.cpp:101 #10 AudioCreator::create(KIO::ThumbnailRequest const&) (this=this@entry=0x55f37e5054a0, request=...) at /usr/src/debug/kio-extras/kio-extras-23.04.1/thumbnail/audiocreator.cpp:179 #11 0x00007f558f6348c9 in ThumbnailProtocol::createThumbnail(ThumbCreatorWithMetadata*, QString const&, int, int, QImage&) (this=this@entry=0x7ffccde07f50, thumbCreator=thumbCreator@entry=0x55f37e5053c0, filePath=..., width=128, height=height@entry=128, thumbnail=...) at /usr/src/debug/kio-extras/kio-extras-23.04.1/thumbnail/thumbnail.cpp:851 #12 0x00007f558f63a5d5 in ThumbnailProtocol::get(QUrl const&) (this=0x7ffccde07f50, url=<optimized out>) at /usr/src/debug/kio-extras/kio-extras-23.04.1/thumbnail/thumbnail.cpp:256 #13 0x00007f558f508a64 in KIO::WorkerSlaveBaseBridge::get(QUrl const&) (this=0x55f37e4f4c40, url=<optimized out>) at /usr/src/debug/kio/kio-5.106.0/src/core/workerbase_p.h:71 #14 0x00007f558f505156 in KIO::SlaveBase::dispatch(int, QByteArray const&) (this=0x55f37e4f4c40, command=67, data=...) at /usr/src/debug/kio/kio-5.106.0/src/core/slavebase.cpp:1257 #15 0x00007f558f4fd2ae in KIO::SlaveBase::dispatchLoop() (this=0x55f37e4f4c40) at /usr/src/debug/kio/kio-5.106.0/src/core/slavebase.cpp:342 #16 0x00007f558f6362c2 in kdemain(int, char**) (argc=<optimized out>, argv=<optimized out>) at /usr/src/debug/kio-extras/kio-extras-23.04.1/thumbnail/thumbnail.cpp:121 #17 0x000055f37d84b1fd in main(int, char**) (argc=5, argv=0x7ffccde08b98) at /usr/src/debug/kio/kio-5.106.0/src/kioslave/kioslave.cpp:145 [Inferior 1 (process 7388) detached] ``` I have built the current plasma5/kf5 branch of plasma-workspace, plasma-desktop, dolphin and kio-extra with kdesrc-build and there could no longer reproduce the issue. Not sure what might have fixed it though. Looks like it's indeed fixed in 5.107. Created attachment 160086 [details]
Crash report from kioslave5
For me it still crashes with 5.107.0 on ArchLinux. Except only on the music library now. The crash with the file open dialog showing my home directory seem resolved (or I moved/deleted the offending file thee, not sure about which). Current system information: Operating System: Arch Linux KDE Plasma Version: 5.27.6 KDE Frameworks Version: 5.107.0 Qt Version: 5.15.10 Kernel Version: 6.4.1-arch2-1 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Xeon® CPU E3-1245 v5 @ 3.50GHz Memory: 31,1 GiB of RAM Graphics Processor: AMD Radeon RX 580 Series Manufacturer: Supermicro Product Name: Super Server System Version: 0123456789 I'm pretty sure I found the issue. At least on my machine it doesn't happen anymore with the fix and before I could reproduce it every time I opened my ~/music folder in Dolphin. I've created a merge request for the fix at https://invent.kde.org/network/kio-extras/-/merge_requests/281 Git commit 3bd4906f2e37456eb296a527913b305ba472b761 by Albert Astals Cid, on behalf of Daniel Schulte.

Pushed by aacid into branch 'master'. thumbnail: Fix heap-use-after-free in AudioCreator::create There is a heap-use-after-free issue in `AudioCreator::create` resulting from storing the pointer to a temporary `QByteArray`'s data() in a pointer and accessing it after the byte-array has been freed (when the the temporary object was created on is over). This fixes it by moving the `QByteArray` onto the stack, thus making it not temporary anymore, keeping it around until its data isn't needed anymore.

SUMMARY kioslave5 crashes when displaying m4a files in Dolphin, which are stored on an mounted NTFS drive. Reproducible, always. When copying these files to a local system folder (BTRFS), kioslave5 does not crash. STEPS TO REPRODUCE 1. Open a folder containing some m4a files, which are stored on an NTFS drive OBSERVED RESULT ``` (gdb) bt #0 __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=11,
