Yes, the problem is, that the profile argument to the AlkOnlineQuoteSource<br>
ctor is a nullptr. This is then used and the crash happens. The cause to<br>
this is, that in AlkOnlineQuotesWidget::Private::slotNewEntry() the<br>
m_profile member is not initialized (nullptr). An assignment happens in<br>
AlkOnlineQuotesWidget::Private::loadProfiles() and <br>
AlkOnlineQuotesWidget::Private::slotLoadProfile() but the list of profiles<br>
in your case seems to be empty, and thus no profile is assigned.<br>
<br>
See MainWindow::MainWindow in onlinequoteseditor.cpp which is part of alkimia<br>
how to load an initial profile which you should do if the list is empty.<br>
