estel: IIRC you promised to open bugs against camera-ui a couple of months ago. It could be that I didn't search correctly, but I just can't find those bug reports on BMO. Your post above is a rant, not a bug report, sorry, not to say I am unable to reproduce what fails on your device. AFAIK you have more than one n900, could you please take one of those, flash it to stock rootfs/eMMC, install ONLY CSSU-T (or CSSU-thumb) and try to reproduce the issue.

camera-ui is not unmaintained, I just don't see bug reports against it which contain enough information for me (or some other guy) to start chasing the bug.

I know your (and marmistrz') device is heavily tweaked and it might be the reason why camera-ui fails for you while it works perfectly reliable for me (and not only me, my GF uses N900 too, so if there is some really big issue I would have heard about it already, lots of times ).
