I confirm this bug. In 4.8.1 and 4.8.2. Doesn't crash if i move messages only. Crash When moving folders.
Created attachment 70826 [details] New crash information added by DrKonqi kmail (4.8.2) on KDE Platform 4.8.2 (4.8.2) using Qt 4.8.1 - What I was doing when the application crashed: Under KMail 4.8.2 (from Kubuntu ppa), I was moving a "big" MailDir archive folder (all mail from one year) to another empty folder --I wanted to change the archive folder organization--. Kmail crashed many times during my reorganization, once for each folder movement, basically ... well, maybe one or two out of ten times, it didn't crash. I hope resulting mail is not corrupt (after restarting KMail, the operation seems to have completed successfully)... There was no hint in the user interface that some operations were under way so while waiting for the directories to dissapear from the old location, I continued work in many cases ... -- Backtrace (Reduced): #6 size (this=0x3000310034) at ../../include/QtCore/../../src/corelib/tools/qvector.h:137 #7 QSortFilterProxyModelPrivate::proxy_to_source (this=0x19897c0, proxy_index=...) at itemviews/qsortfilterproxymodel.cpp:370 #8 0x00007f07eb910abd in QSortFilterProxyModel::mapToSource (this=<optimized out>, proxyIndex=<optimized out>) at itemviews/qsortfilterproxymodel.cpp:2502 #9 0x00007f07eb911d4d in QSortFilterProxyModelPrivate::store_persistent_indexes (this=<optimized out>) at itemviews/qsortfilterproxymodel.cpp:996 #10 0x00007f07eb912b73 in QSortFilterProxyModelPrivate::_q_sourceLayoutAboutToBeChanged (this=0x19897c0) at itemviews/qsortfilterproxymodel.cpp:1244

Thank you for your report. Although I still see this happening within a maildir resource with KMail and Akonadi 16.04, I am closing this report as KDEPIM SC 4 and Akonadi 1 is unmaintained. So this bug report contains outdated backtraces. I am intending to report the bug for KMail and Akonadi 16.04, but feel free to beat me to it and note it here. Also please note whether you are moving folders within a Maildir resource or within an IMAP account. Thanks, Martin
