Please correct me if you were not using VNC. I mix both vnc and rdp, but I do believe the tab I closed was using VNC, yes. Lots of similar or identical reports: #226304, #227501, #229295, #231773, #233780, #209932, #220262, perhaps others when you search for "krdc" and then "crash". For me, it's very trivial to reproduce - connect a few sessions (VNC, RDP), close the tab, connect to the same IP where you just closed the tab... Do it for a while, krdc will crash pretty fast. 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. |
Application: krdc (4.4.00 (KDE 4.4.0)) KDE Platform Version: 4.4.00 (KDE 4.4.0) (Compiled from sources) Qt Version: 4.6.2 Operating System: Linux 2.6.31-gentoo-r6 i686 Distribution (Platform): Gentoo Packages -- Information about the crash: I pressed CTRL+W, with the intent of closing a firefox tab. Instead this closed a KRDC tab, and immediately afterwards, KRDC went down all together. The crash does not seem to be reproducible. -- Backtrace: Application: KRDC (krdc), signal: Segmentation fault [Current thread is 1 (Thread 0xb59d3700 (LWP 30402))] Thread 3 (Thread 0xb3243b70 (LWP
