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. (In reply to comment #1) > 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)? Upgraded my kubuntu and testet with 4.5.1. Have not had any crashes since. Sorry for my late reply, been way behind :-) |
Application: krdc (4.4.2 (KDE 4.4.2)) KDE Platform Version: 4.4.2 (KDE 4.4.2) Qt Version: 4.6.2 Operating System: Linux 2.6.32-21-generic x86_64 Distribution: Ubuntu 10.04 LTS -- Information about the crash: Sometimes when closing krdc it crashes. It doesnt happen when using the app, only when closing. The problem has been there before, when running kubuntu 9.10, now running 10.4. It happens mostly if i've had more than 1 connection open. It almost never happen if I disconnect all connections before closing. The crash can be reproduced some of the time. -- Backtrace: Application: KRDC (krdc), signal: Segmentation fault [Current thread is 1 (Thread 0x7f51c74c3760 (LWP 1656))] Thread 3 (Thread 0x7f51b5230710 (LWP 1657)): #0 0xffffffffff60014c in ??
