As pointed out by a duplicate reported, the same crash happens in Kate,
see bug 305913, so it most probably is a QtScript issue.

I confirm the bug with QT 4.8.2 and KDE 4.9!

WORKAROUND: downgrade QT to 4.8.1 !
With QT 4.8.1, the bug doesn't show up, so it must be a QT (script) issue as said by #7

I commented it in the original JSC crash bug - https://bugreports.qt-
project.org/browse/QTBUG-23871 as it seems the patch is causing this
issue (according to the comment #9).
