is QtPDF installed? maybe the dependency was not updater properly (In reply to Alexander Stippich from comment #1) > is QtPDF installed? maybe the dependency was not updater properly Yes, qt6-qtpdf 6.7.2 is installed from Source qt6-qtwebengine-6.7.2-1.fc40.src.rpm, and skanpage should locate it OK: % ldd /usr/bin/skanpage| rg -i pdf libQt6Pdf.so.6 => /lib64/libQt6Pdf.so.6 (0x00007fcbae800000) A possibly relevant merge request was started @ https://invent.kde.org/utilities/skanpage/-/merge_requests/81 Git commit 7b06fb345d42712f1ac209bc2b3f4468e42a29f8 by Alexander Stippich.

Created attachment 171618 [details] trivial PDF (exported from LibreOffice Writer) that crashes Skanpage on import SUMMARY See Summary STEPS TO REPRODUCE 1. Open Skanpage 2. Click Import 3. Navigate to a PDF and open OBSERVED RESULT Immediate crash. I repeated with a different PDF. The KDE Crash Reporter started up both times. The first time I don't know where the report went, the second time I tried to see the backtrace and it overloaded my 8GB Thinkpad, so I killed it. I ran skanpage a third time under gdb and imported the attached trivial PDF, and here's the partial backtrace: Thread 1 "skanpage" received signal SIGSEGV, Segmentation fault. 0x00007ffff7f8f28d in KSaneCore::Option::value (this=0x0) at /usr/src/debug/ksanecore-24.05.0-1.fc40.x86_64/src/option.cpp:116 116 if (d->option != nullptr) { Missing separate debuginfos, use: dnf debuginfo-install skanpage-24.05.0-1.fc40.x86_64 (gdb) bt #0 0x00007ffff7f8f28d in KSaneCore::Option::value (this=0x0) at /usr/src/debug/ksanecore-24.05.0-1.fc40.x86_64/src/option.cpp:116 #1 0x000055555558fb98 in Skanpage::importFile (this=0x7fffffffd720, fileUrl=...) at /usr/src/debug/skanpage-24.05.0-1.fc40.x86_64/src/Skanpage.cpp:691 #2 Skanpage::qt_static_metacall (_o=0x7fffffffd720, _c=<optimized out>, _id=<optimized out>, _a=0x7fffffff9cd8) at /usr/src/debug/skanpage-24.05.0-1.fc40.x86_64/redhat-linux-build/src/skanpage_autogen/include/moc_Skanpage.cpp:463 #3 0x0000555555591574 in Skanpage::qt_metacall (this=0x7fffffffd720, _c=QMetaObject::InvokeMetaMethod, _id=33, _a=0x7fffffff9cd8) at /usr/src/debug/skanpage-24.05.0-1.fc40.x86_64/redhat-linux-build/src/skanpage_autogen/include/moc_Skanpage.cpp:631 #4 0x00007ffff63b3caa in QQmlObjectOrGadget::metacall ... EXPECTED RESULT 1. Don't crash. 2. At a minimum Skanpage should detect mime type, sniff the file, etc. and warn something like "Unsupported file type (application/pdf); supported image types include JPG, PNG, ..." I don't know if it should have a "[Proceed to scan anyway]" button. 3. (Enhancement) Skanpage should support PDF files. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 6.1.2 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.2 (built against 6.7.1) ADDITIONAL INFORMATION gImageReader (gimagereader-qt5) can scan PDFs fine. It's probably using libpoppler to render PDF files and examine their structure to directly extract any text.
