The upgrade to 12.04 (64 bit, KDE 4.8.2) went great for me - not a single problem with any application (and I run lots), except one: ssh.
For years, I have been logging into my lab machine (lots of HW attached) via ssh -Y and I could run all X-applications wihout any problems over Ethernet. Not anymore :mad:. Every time I try to start a Qt-based (KDE) application remotely it crashes with
*** glibc detected *** konsole: malloc(): memory corruption: 0x08d94480 ***
on the remote side (the ssh-login itself shows no signs of errors). Happens at least for konsole (above example), dolphin, kdevelop (the ones I use the most in this mode), and my own Qt-based application. The only application I use often that still works remotely is gschem (from what I can tell not a Qt-based app). As expected, results for ssh -X and ssh -Y are identical.
BTW, the remote lab machine still runs 11.10 (32 bit, KDE 4.7.4), and I can do a ssh -Y from that machine to the one running 12.04 with full X-functionality, only from 12.04 to 11.10 does not work.
Did anybody else notice this problem? Found a sloution??
