Summary: bug using vnc
Initial Comment:
rather a qemu-bug:
after closing the vnc-window (because it doesn't resize if the guest changes
the resolution) I get this:
Program received signal SIGSEGV, Segmentation fault.
0x0805022a in main_loop_wait (timeout=165391440) at
/usr/src/kernel/kvm-18/qemu/vl.c:6203
6203 ioh->fd_write(ioh->opaque);
(gdb) print ioh
$1 = (IOHandlerRecord *) 0x9e8a328
(gdb) print *ioh
$2 = {fd = 166535168, fd_read_poll = 0, fd_read = 0x80b6800 <vnc_client_read>,
fd_write = 0, opaque = 0x9db1e40, ufd = 0x0,
next = 0x9dbac50}
simple to fix:
