This appears to be related to the UPX compression used by Hamachi (/usr/bin/hamachi is a UPX-compressed executable). A workaround (although not really a fix, as this shouldn't be necessary) is:
1) sudo aptitude install upx-ucl 2) sudo upx -d /usr/bin/hamachi This will restore Hamachi to its working state in Karmic. However, LogMeIn have recently updated the Windows client and I've emailed them about Linux support, they assure me that Linux support is continuing and they're working on a Linux client to match the features of the Windows version, whether this fix will still be needed and/or valid in the new version I have no idea. I haven't submitted this bug report to LogMeIn as I'm not sure where it should go; LogMeIn's product worked in previous Ubuntu releases with no problems, and still does when decompressed, so I don't think it's their issue, it sounds more like a Ubuntu/kernel upstream issue to me?
