--- Comment #2 from CUONG <[email protected]> --- Thank you for the guidance. I am providing the requested information and an updated backtrace with the required debug symbols. Dolphin: 25.12.3 KDE Frameworks: 6.24.0 Qt: Using 6.10.2 and built against 6.10.2 Ubuntu 26.04 LTS (Wayland) Build ABI: x86_64-little_endian-lp64 Kernel: linux 7.0.0-22-generic Regarding the debug symbols, I have installed the necessary packages (-dbgsym) to ensure a clearer backtrace. Here is the updated output: ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Thread 1 "dolphin" received signal SIGSEGV, Segmentation fault. 0x00007ffff6d93348 in KJob::kill(KJob::KillVerbosity) () from /usr/lib/x86_64-linux-gnu/libKF6CoreAddons.so.6 (gdb) bt full #0 0x00007ffff6d93348 in KJob::kill(KJob::KillVerbosity) () from /usr/lib/x86_64-linux-gnu/libKF6CoreAddons.so.6 No symbol table info available. #1 0x00007ffff7a9ad7f in KIO::FilePreviewJob::timerEvent (event=<optimized out>, this=<optimized out>) at /usr/src/kf6-kio-6.24.0-0ubuntu1/src/gui/filepreviewjob.cpp:759 No locals. #2 KIO::FilePreviewJob::timerEvent (this=0x5555565683d0, event=<optimized out>) at /usr/src/kf6-kio-6.24.0-0ubuntu1/src/gui/filepreviewjob.cpp:755 No locals. #3 0x00007ffff53db406 in QObject::event (this=<optimized out>, e=<optimized out>) at /usr/src/qt6-base-6.10.2+dfsg-7/src/corelib/kernel/qobject.cpp:1388 __PRETTY_FUNCTION__ = <optimized out> #4 0x00007ffff63a0b7f in QApplicationPrivate::notify_helper (this=<optimized out>, receiver=0x5555565683d0, e=0x7fffffffba90) at /usr/src/qt6-base-6.10.2+dfsg-7/src/widgets/kernel/qapplication.cpp:3305 consumed = false filtered = false threadData = <optimized out> #5 0x00007ffff5390098 in QCoreApplication::notifyInternal2 (receiver=0x5555565683d0, event=0x7fffffffba90) at /usr/src/qt6-base-6.10.2+dfsg-7/src/corelib/kernel/qcoreapplication.cpp:1109 d = <optimized out> threadData = 0x55555570c250 selfRequired = <optimized out> result = false cbdata = {0x5555565683d0, 0x7fffffffba90, 0x7fffffffb9ff} scopeLevelCounter = {threadData = 0x55555570c250} #6 0x00007ffff5516319 in QTimerInfoList::activateTimers (this=0x5555557257e0) at /usr/src/qt6-base-6.10.2+dfsg-7/src/corelib/kernel/qtimerinfo_unix.cpp:426 e = {<QEvent> = {_vptr.QEvent = 0x7ffff57d2c98 <vtable for QTimerEvent+16>, static staticMetaObject = {d = {superdata = {direct = 0x0}, stringdata = 0x7ffff5654248 <QEvent::qt_staticMetaObjectStaticContent<(anonymous namespace)::qt_meta_tag_ZN6QEventE_t>+1512>, data = 0x7ffff5653c60 <QEvent::qt_staticMetaObjectStaticContent<(anonymous namespace)::qt_meta_tag_ZN6QEventE_t>>, static_metacall = 0x0, relatedMetaObjects = 0x0, metaTypes = 0x7ffff57c96a0 <QEvent::qt_staticMetaObjectRelocatingContent<(anonymous namespace)::qt_meta_tag_ZN6QEventE_t>>, extradata = 0x0}}, t = 1, m_posted = false, m_spont = false, m_accept = true, m_unused = false, m_reserved = 0, m_inputEvent = 0, m_pointerEvent = 0, m_singlePointEvent = 0}, m_id = (unknown: 0x6a000013)} currentTimerInfo = 0x5555561f5b50 now = std::chrono::_V2::steady_clock time_point = { 20461500350057ns } stillActive = { __now = <synthetic pointer>std::chrono::_V2::steady_clock time_point = { 20461500350057ns }} it = <optimized out> maxCount = <optimized out> n_act = 1 --Type <RET> for more, q to quit, c to continue without paging-- ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Regarding the issue, I want to clarify that I do use the file preview feature daily. I am not very tech-savvy and I am still learning how these debugging processes work, so I apologize if my previous report was incomplete. I discovered that the crash consistently happens when previews are enabled, but I would really like to keep using this feature as it is essential for my workflow. I truly appreciate the hard work you and the KDE team put into making this software better. Please let me know if there are any updates or if you need any further information from my side.
