Created attachment 181877 [details] Full backtrace (bt full) from coredumpctl gdb with debug symbols SUMMARY: Resuming a paused Dolphin file transfer (via KDE Connect) after switching WiFi access points causes Dolphin, Kontact, and kioworker to crash due to MIME data corruption. DESCRIPTION: While copying files from my Android phone to my desktop using Dolphin over KDE Connect (kdeconnect:// KIO path), I paused the transfer using the Plasma job progress notification popup (the interactive transfer UI in the system tray). The transfer was initiated directly from Dolphin by dragging files from the phone's KDE Connect mount to a local folder. While the transfer was paused, I switched my phone to a different WiFi access point (same LAN, different subnet). Upon resuming the transfer from the notification popup, Dolphin, Kontact, and kioworker all crashed immediately. Backtrace shows the crash originates in QMimeData handling, with QXcbClipboard::getSelection(), QInternalMimeData::retrieveData(), and KUrlMimeData::urlsFromMimeData() involved — suggesting a stale or corrupted MIME data object, likely tied to the invalidated kdeconnect:// connection after the network handoff. STEPS TO REPRODUCE: 1. Start a file transfer from phone to PC using Dolphin (with KDE Connect as the transport) 2. Pause the transfer from the system tray job popup 3. Switch the phone to a different WiFi access point (same LAN, different subnet) 4. Resume the transfer via the same popup 5. Click "Paste" or interact with the clipboard in Dolphin OBSERVED RESULT: Immediate crash in Dolphin with a SIGABRT in QInternalMimeData::retrieveData() EXPECTED RESULT: Transfer should fail gracefully, or clipboard state should be cleared without crashing SOFTWARE/OS VERSIONS: - Operating System: Arch Linux - KDE Plasma Version: 6.3.5 - KDE Frameworks Version: 6.14.0 - Qt Version: 6.9.0 - Kernel Version: 6.14.7-arch2-1 (64-bit) - Graphics Platform: X11 - Processors: 32 × AMD Ryzen 9 5950X - Memory: 124.9 GiB RAM - Graphics: AMD Radeon RX 6900 XT ADDITIONAL INFORMATION: Full backtrace from `coredumpctl gdb dolphin` is attached.
