I've tracked this to libtop deficiency reading larger /proc/cpuinfo.
This minimal libgtop patch fixes/workarounds it for me.
Yanko, while using g_file_get_contents() is better in principle, I don't see why it would help here since the /proc/cpuinfo in question is only ~5K and so fits within the 16K buffer.
(Also the patch needs to free the returned contents).
Soren, I tried to explain it in the upstream bugreport. The way libgtop tries to read the file (single read) comes up short, around 4K, it has to be read again to get the next part and libgtop doesn't do that. I've been told this is to be expected when reading /proc files, something about kernel page size.
libgtops file_to_buffer needs to get smarter about this or it should just drop the whole thing and use glib which manages to get the whole file contents in tact.
