            Bug ID: 345618
           Summary: Powerdevil crash from idle desktop.
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: matthew at mjdsystems.ca

Application: kded5 ()
 (Compiled from sources)
Qt Version: 5.4.0
Operating System: Linux 3.19.0-gentoo x86_64
Distribution: "NAME=Gentoo"

-- Information about the crash:
When I picked up my laptop to begin using it, kded crashed in powerdevil.  It
appears to have crashed in this function:
void Core::onResumingFromIdle()
{
    // Wake up the actions in which an idle action was triggered
    QList< Action* >::iterator i = m_pendingResumeFromIdleActions.begin();
    while (i != m_pendingResumeFromIdleActions.end()) {
        (*i)->onWakeupFromIdle(); // <<--- On this line
        i = m_pendingResumeFromIdleActions.erase(i);
    }
}

I haven't seen it before, so it may just be an unlikely race somewhere.

-- Backtrace:
Application: kded5 (kded5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
