Comment 1 Christoph Feck 2010-01-31 02:40:30 UTC

SVN commit 1082643 by cfeck:

Disconnect timers early

When a TerminalDisplay is destroyed, the timers are still active
until they are deleted by QObject, so they could fire when anything
in the QWidget or QObject destructor processes events.

BUG: 208199
