Volker, could it be a symptom of the bug I fixed with r1060671? That one also had an invalid memory access at QSharedDataPointer<Akonadi::EntityPrivate>::operator=. That fix should also be merged to trunk. SVN commit 1066751 by tmcguire: SVN_MERGE CCBUG: 219626 Merged revisions 1060404,1060670-1060671 via svnmerge from svn+ssh://tmcguire@svn.kde.org/home/kde/branches/work/akonadi-ports/kdepimlibs ........ r1060404 | tmcguire | 2009-12-08 21:04:13 +0100 (Tue, 08 Dec 2009) | 3 lines Add test for walking the parent collections after parsing a collection. Fails because of some uninitalized memory reads. ........ r1060670 | tmcguire | 2009-12-09 16:35:06 +0100 (Wed, 09 Dec 2009) | 5 lines Cleanup the test. I hope adjusting the HRID test was ok, I guess adding another test caused the negative collections to be even more negative. ........ r1060671 | tmcguire | 2009-12-09 16:37:59 +0100 (Wed, 09 Dec 2009) | 8 lines Fix crash in ProtocolHelperTest::testParentCollectionAfterCollectionParsing(). See comments for details. This is the best fix I could come up with, I hope it doesn't hurt performance too much. (And the lesson we have learned: Don't cast pointers to references and then return them) Volker, you'll want to review this. ........ _M .
