Thanks for the information
Hi,
Just before the crash I see in .xsession-errors I the following message:
dolphin(2047)/kio (KDirModel): Items emitted in directory KUrl("file:///var/tmp/kdecache-martin") but that directory isn't in KDirModel! Root directory: KUrl("file:///home/martin")
Maybe it's relevant or helpful.

SVN commit 1064817 by dfaure: Fix 213799 again (kio doesn't notice changes in a symlink-to-a-directory) without introducing the 219547 crash in treeviews (due to KDirModel seeing unexpected resolved urls). The new strategy is: rather than resolve the url right away (and emit wrong items), we just store the "resolved_path -> known_path(s)" association in a QHash, and look that up when we are notified of changes. Fixed for: 4.4 RC1 BUG: 219547 CCBUG: 213799 M +52 -14 kio/kdirlister.cpp M +14 -0 kio/kdirlister_p.h M +3 -0 tests/kdirlistertest.cpp M +8 -0 tests/kdirmodeltest.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1064817 *** Bug 221353 has been marked as a duplicate of this bug. *** Fix backported for 4.3.5. Hi, Updated to KDE 4.3.95 (aka 4.4 rc2) and I can confirm that the issue is solved. Thanks for the good work! Martin Kho |
