[Kolab-devel] [issue1990] [Kontact enterprise rev. 711604] Crash in ImapAccountBase::cancelMailCheck()

[Gunnar Wrobel]

New submission from Gunnar Wrobel <p at rdus.de>:

Taking this from issue1955 to a new bug.

I did just add a few debug statements into the function where the code crashes:

  void ImapAccountBase::cancelMailCheck()
  {
    QMap<KIO::Job*, jobData>::Iterator it = mapJobData.begin();
    while ( it != mapJobData.end() ) {
      kdDebug(5006) << "cancelMailCheck: job is cancellable: " <<
(*it).cancellable << endl;
      if ( (*it).cancellable ) {
	kdDebug(5006) << "cancelMailCheck2: job is cancellable: " << (*it).cancellable
<< endl;
        it.key()->kill();
        QMap<KIO::Job*, jobData>::Iterator rmit = it;
	kdDebug(5006) << "cancelMailCheck3: job is cancellable: " << (*it).cancellable
<< endl;
        ++it;
	kdDebug(5006) << "cancelMailCheck4: job is cancellable: " << (*it).cancellable
<< endl;
        mapJobData.remove( rmit );
        // We killed a job -> this kills the slave
        mSlave = 0;
	kdDebug(5006) << "cancelMailCheck5: job is cancellable: " << (*it).cancellable
<< endl;
      } else
        ++it;
    }

The debugging output looks like this then:

kmail: Closing last KMMainWin: stopping mail check
kmail: cancelMailCheck: job is cancellable: true
kmail: cancelMailCheck2: job is cancellable: true
*** KMail got signal 11 (Crashing)

So maybe

        it.key()->kill();

is killing it?

Does this help or is more debugging information needed?
