I believe, vmlinuz-3.2.18 did not came with any Debian package (even 
sid/unstable includes up to 3.2.0). Maybe you compiled it yourself? In 
any case, the initial error is clearly 3.2.18's fault. If you have no 
particular reason to use a custom kernel, I recommend you to stick to 
the repository.
The installation of xen-qemu-dm-4.0 was supposed not to cause any 
troubles, but my hypotheses is that it somehow triggered update-grub 
re-creation (some unconfigured packages was present, maybe? there are 
several ways) and broke your previously working configuration.
You said, you got errors while installing xen-qemu-dm-4.0. They are 
probably still in /vat/log/dpkg.log or /var/log/apt or 
/var/log/aptitude. If what exactly happened is still relevant, i would 
look for the answer there. If you have not touched your grub.cfg, it's 
last modification date will tell you where to look in the logs.
If you just need this to work, please consider removing all 
weired/unused kernel images, so update-grub can have less to mess with. 
Beware, some of those kernels might be still needed by your DomUs.
