exmap permission errors

[Charles Brunet]

Binary package hint: exmap

Installed exmap and exmap-modules-source, compiled module and installed it.
Hardy Heron, AMD64 version.

Errors when running: gksudo gexmap:

It then shows zero for all processes.

Did you try to sudo it?
I got a similar error:

Aborted

Starting it with sudo however worked (in that sense that it started the gui).
Should yield an appropriate error-message though.

The bug is still valid because the GUI shows 0,0 for all values and I guess my system might be using slightly more RAM ;)

Do you experience a apport crash report? Thank you!

[Charles Brunet (cbrunet)]

I no longer use this software, so can cannot tell if the bug still is relevant or not.
