SUMMARY When the clipboard is empty (! QClipboard ::mimeData (QClipboard::Clipboard)), Konsole crashes on paste. STEPS TO REPRODUCE 1. { konsole --platform vnc; } 2. Connect to the VNC server! 3. Tell Konsole to paste! OBSERVED RESULT #0 0x00007ffff6900d6b in QMimeData::hasUrls (this=this@entry=0x0) at ../../include/QtCore/../../src/corelib/text/qstring.h:967 967 Q_DECL_CONSTEXPR inline QString(QStringDataPtr dd) : d(dd.ptr) {} #1 0x00007ffff7e995ff in Konsole::TerminalDisplay::pasteFromClipboard (this=0x555555973810, appendEnter=<optimized out>) at /usr/src/debug/konsole-22.12.0/src/terminalDisplay/TerminalDisplay.cpp:2360 2360 if (!mimeData->hasUrls()) { // fast path if there are no urls EXPECTED RESULT The paste command should be disabled when the clipboard is empty.
