Here's the code protion that throws the error, but I don't grok enough of the code to tell why. Help?

void DvbPanel::checkTimers() { int i, j, ret; bool live=false; RecTimer *t; ChannelDesc *chan; QDateTime cur=QDateTime::currentDateTime(); DvbStream *d;

for ( i=0; i<(int)timers.count(); i++ ) { t = timers.at(i); if ( t->running ) continue; if ( t->begin<=cur && cur<t->begin.addSecs(QTime().secsTo(t->duration)) ) { chan = 0; for ( j=0; j<(int)channels.count(); j++ ) { if ( channels.at(j)->name==t->channel ) { chan = channels.at(j); break; } } if ( !chan ) continue; d = getWorkingDvb( 3, chan ); live = false; if ( d ) ret = d->canStartTimer( live, chan ); else ret = -1; if ( ret==0 ) { if ( live ) { stopLive(); emit dvbStop(); } if ( d->startTimer( chan, dvbConfig->recordDir, dvbConfig->sizeFile, t, dvbConfig->filenameFormat ) ) { KProcess proc; proc << QDir::homeDirPath()+"/bin/kaffeine_recording"; proc << "On"; proc.start( KProcess::DontCare ); t->running = 1; if ( timersDialog ) emit timersChanged(); saveTimerList(); i--; } else fprintf( stderr, "start timer failed!!!\n" ); } else fprintf( stderr, "Cant start timer !!!\n" ); } else if ( t->mode ) { if (t->begin.addSecs(t->duration.hour()*3600+t->duration.minute()*60+60)<cur) { updateModeTimer( t ); if ( timersDialog ) emit timersChanged(); } } } }
