There is some problem with 1.5.0 release, starting multiload-ng fails, so I tried to run in gdb (Ubuntu 12.04 32-bit):

Thanks for the detailed report!

Multiload-ng expects a value that is not present in your system. This may be related to Ubuntu version, like other previous issues.

Can you please post the contents of your /proc/meminfo?

OK, this has a trivial solution. Unfortunately it's hard for me to track problems like this, because it's a old system that I don't have access to, so I must wait for a bug report to fix them.

With the next commit you can use Multiload-ng again (unless other bugs arise :smile:). You will have to build from source until next release. thank you again for reporting!
