[Bug 803534] New: KRDC crashes when connecting to a VNC server

https://bugzilla.novell.com/show_bug.cgi?id=803534 https://bugzilla.novell.com/show_bug.cgi?id=803534#c0 Summary: KRDC crashes when connecting to a VNC server Classification: openSUSE Product: openSUSE 12.2 Version: Final Platform: x86-64 OS/Version: openSUSE 12.2 Status: NEW Severity: Critical Priority: P5 - None Component: KDE4 Applications AssignedTo: kde-maintainers@suse.de ReportedBy: vfernandez@barracuda.com QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Opera/9.80 (X11; Linux x86_64) Presto/2.12.388 Version/12.12 After updating to KDE SC 4.10 using the KDE:Release:410 repository, whenever I connect to my tightvnc-1.3.10 server that runs openSUSE 12.2, KRDC crashes. This did not happen in KDE SC 4.9. The connection to RDP servers works properly. This bug report was already posted in bugs.kde.org, and has been confirmed by ilmc888. I'm posting it here on request by Urs Wolfer from KDE, who suggests it's a packaging issue in openSUSE: https://bugs.kde.org/show_bug.cgi?id=314504 KRDC crashes in thread 2.
