Comment 1 Frank Reininghaus 2012-10-26 10:48:26 UTC

Thanks for the bug report! Looks like a duplicate of bug 306459 (fixed in KDE 4.9.3) to me. I don't quite understand though why this should happen after opening a new tab. It should only happen if a new DolphinView is created while some other window (not Dolphin's main window) has the focus.

Comment 2 pfodea 2012-10-27 00:14:21 UTC

Thanks. Will check it out. Part of the problem may be I'm living in China and may be incursions by interfering hackers who only have a partial grasp of the English or the misnamed Internet Bureau who are tightening 'supervision' in a general way as crucial CPC Congress approaches. Even with firewall on.

Thanks for the bug report! Looks like a duplicate of bug 306459 (fixed in KDE
4.9.3) to me. I don't quite understand though why this should happen after
opening a new tab. It should only happen if a new DolphinView is created while
some other window (not Dolphin's main window) has the focus.

Comment 3 Frank Reininghaus 2012-11-23 15:41:50 UTC

Please reopen if you still get this crash in KDE 4.9.3 or later. Thanks!
