"I run ubuntu 9.04 server guest on VirtualBox 2.2.4 r47978 on a Windows Vista SP 1 host. tuxpaint ends abnormally with not notification."
It's tuxpaint 0.9.20 and is giving sigsgv.
ubuntu kernel: [ 960.596943] tuxpaint: segfault at 3eeeeef7 ip b7b18dc3 sp bfa39234 error 4 in libc-2.9.so[b7aa9000+15c000]
I've no idea how to get any useful info out of this setup. We may have to ask him to re-enable apport, and install debug packages.
