parsing error

While trying to render a chart I get something like this:

[~] pybootchartgui -i No path given, trying /var/log/bootchart.tgz parsing '/var/log/bootchart.tgz' parsing 'header' parsing 'dmesg' parsing 'cmdline2.log' parsing 'proc_diskstats.log' parsing 'proc_stat.log' parsing 'taskstats.log'

I've tested on 2 kernels (one with initrd, one without), always the same. Running Arch Linux and Python 2.6.5.

How interesting :-) Any chance you can attach your bootchart .tar.gz ? it sounds like there were no samples in taskstats.log; I guess we should handle that more sensibly - but the real question is: why were there no samples ? :-)

Wops, my bad ;)

Yep - no taskstat samples at all: most odd. I've committed a fix that will exit earlier when there are no samples. Of course, why there are none - I have no idea :-) Did you get a full boot chart in the end, or not ?

I've get something like this: http://wstaw.org/w/70e/ No dump in /tmp.
