This is probably related to bug 220453. Thanks SVN commit 1130864 by murrant: Workaround for a common crash when disconnecting a VNC connection. This is included in KDE SC 4.5 Beta 2. Please test and confirm. The patch can be found here: http://reviewboard.kde.org/r/4041/diff/raw/ REVIEW: 4041 CCBUG: 220262 CCBUG: 220456 CCBUG: 220688 CCBUG: 229295 CCBUG: 229944 CCBUG: 230478 CCBUG: 231773 CCBUG: 232762 CCBUG: 233780 M +15 -16 mainwindow.cpp M +3 -3 vnc/vncclientthread.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1130864 We have fixed some crashes in the VNC plugin recently. Can you still reproduce this issue with a recent version of KRDC (from KDE SC 4.5 or later)? Closing as fixed since nobody can reproduce this crashes anymore with the fixes from KRDC 4.5. |
