[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[André Stein (andre-stein-1985)]

In Qt 4.8.4 some things have been fixed which introduced crashes in kate and kdevelop due to bugs in QtScript/QTDeclarative. As suggested by the developers in the following bug reports

https://bugs.kde.org/show_bug.cgi?id=297661
https://bugs.kde.org/show_bug.cgi?id=309580

an update to Qt 4.8.4 should help.

[Maciej Cencora (m-cencora)]

Unfortunately a fix for QtScript crash is reverted in our packages with kubuntu_38_revert_fix_jit_crash.diff
so https://bugs.kde.org/show_bug.cgi?id=297661 still affects all ubuntu/kubuntu users.

What was the reason to revert this fix?
