Comment 4 for bug 743337

it seems it fails just sometimes - I noticed it not working again in chrome, opened kmail to find this bug nr, and it started to work. even in the same instance of chrome.

I would appreciate any thoughts of what should I use to get more info or how should I debug it?..
why is it 0 only, that ignores the numlock? and why just sometimes? (and also I dont know how to force it to stop working for debugging :) )

I could leave some logging script running, but what should it check?
