Comment 1 Achim Bohnet 2015-11-23 13:59:06 UTC

More specific korganzier 15.08.2does crash after:
 * akonadictl start
or
 * clicking on the 'Start' button in the center of grey area, that korganizer shows when akonadi is stopped.

[kmail and kaddressbook survive a akonadi restart]

Comment 2 David Faure 2016-07-25 21:46:13 UTC

Also happens when disabling/re-enabling some calendars, same backtrace.

Comment 7 David Faure 2016-07-25 21:48:24 UTC

I have reduced the issue to this testcase, which crashes indeed.

    QVector<int> vec;
    vec.erase(std::remove(vec.begin(), vec.end(), 42), vec.end());
    vec.reserve(0);

Comment 8 David Faure 2016-07-25 21:59:14 UTC

Found a Qt bug report about this, reopened it with more details, https://bugreports.qt.io/browse/QTBUG-51758.

Meanwhile it's quite pointless to do all this for an empty container, I'll add an if() in kcalcore, good for performance, not just as a workaround.
