Bug Description

Binary package hint: maximus

This crash occurs while running 'harware testing', in particular when performing the video test (
SMPTE 100% color bars). This occurs every time I run this test. Here is the console output from the second attempt. The 'null' window appears when the video test begins, and it crashes immediately thereafter.

Hi,

Thanks for the report. Do you know what it means to have a
NULL class? Should maximus act on this window?

Thanks,

James

Hi,

I've reproduced this now, it's hwtest-gtk that triggers it.

The branch attached to this report

lp:~james-w/netbook-remix/maximus.handle-null-crash

should fix the crash, though excluding these windows
may be the things to do. I can't find any documentation
on what it might mean though.

Thanks,

James

Thanks James, I've merged your branch and spun a new release (0.4.1) for hardy & intrepid, both of which should be building in the ppa now.

Can we update the intrepid package as this is a critical bug?

Sure, poke me on IRC if I haven't done it by the end of the day.

Is there anything else in this release?

Thanks,

James
