Seems like it is https://bugs.kde.org/show_bug.cgi?id=398320 that has gotten re-introduced somehow. *** This bug has been marked as a duplicate of bug 398320 *** |
At fc35d8345b2e8e77d35fbde2a38bb1cb79a7c247. I'm not 100% sure what I was doing when it happened, I think I hit the mouse button while pressing some unknown key. Interesting part of stack trace: #0 0x00007f229989c615 in raise () from /usr/lib/libc.so.6 #1 0x00007f2299885862 in abort () from /usr/lib/libc.so.6 #2 0x00007f2299ab99ac in QMessageLogger::fatal(char const*, ...) const () from /usr/lib/libQt5Core.so.5 #3 0x00007f2299ab8d59 in qt_assert(char const*, char const*, int) () from /usr/lib/libQt5Core.so.5 #4 0x00007f2295c6c837 in Konsole::Screen::copyLineToStream (this=0x557577c178c0, line=<optimized out>, start=21, count=1, decoder=0x7ffefe53ea30, appendNewLine=<optimized out>, options=...) at /usr/include/qt/QtCore/qvector.h:478 #5 0x00007f2295c9481f in Konsole::Screen::writeToStream (this=0x557577c178c0, decoder=0x7ffefe53ea30, startIndex=<optimized out>, endIndex=<optimized out>, options=...) at /usr/src/debug/konsole/src/Screen.cpp:1297 #6 0x00007f2295c960c2 in Konsole::Screen::text (this=this@entry=0x557577c178c0, startIndex=34599, endIndex=34599, options=options@entry=...) at /usr/src/debug/konsole/src/Screen.cpp:1262 #7 0x00007f2295c961d3 in Konsole::Screen::selectedText (this=0x557577c178c0, options=options@entry=...) at /usr/src/debug/konsole/src/Screen.cpp:1243 #8 0x00007f2295c7eadf in Konsole::Emulation::checkSelectedText (this=0x55757783e710) at /usr/include/qt/QtCore/qflags.h:121 #9 0x00007f2299d12a26 in ??

Variables available at "int copied = copyLineToStream([...]" in Screen::writeToStream(): count = 1 decoder = (Konsole::TerminalCharacterDecoder *) 0x7ffefe53ea30 appendNewLine = false options = options (PreserveLineBreaks) In copyLineToStream: start = 21 lineLength = 113 screenLine = 306 (so we are in the not 'line < _history->getLines()' branch) length = optimized out (which could mean we're after where it is defined, maybe) data = optimized out i = not in current context (so not in any of the for loops) The confusing thing is, though, that I can't find any QVectors in that scope, much less any code calling QVector::remove().
