this is a minimal diff that fixes it, but someone who's familiar with this code should verify that everything that calls getCharacterPosition() is correct. diff --git src/TerminalDisplay.cpp src/TerminalDisplay.cpp index 5b437937..a2d5ad17 100644 --- src/TerminalDisplay.cpp +++ src/TerminalDisplay.cpp @@ -2528,7 +2528,7 @@ void TerminalDisplay::extendSelection(const QPoint& position) int charColumn = 0; int charLine = 0; - getCharacterPosition(pos, charLine, charColumn, true); + getCharacterPosition(pos, charLine, charColumn, false); QPoint here = QPoint(charColumn, charLine); QPoint ohere;
thanks
I think this is the most correct fix (I'd feel better if I refactored everything, but that's for another day): https://phabricator.kde.org/D17740

We had to revert https://commits.kde.org/konsole/ef3773b8753b7553fc09c8cb020925388b05bc73because it caused a critical regression in the stable branch: Bug 403117. Re-opening.
I can't seem to replicate the crash on the latest konsole from git master. I've highlighted a whole blank line and then tried to drag it to the right. Can you please confirm if this is still an issue, thanks.
