Ok, I just uploaded new version of pyKake to the Extras-devel, the bulb mode problem with Pentax should be now solved, at least as far as I can test it by myself, so I waiting the comments. I also changed the bugtracker to this thread and did some magic with post remove script.

Edit1: OK, in version pyKake 0.5.0-7 was pretty nasty typo in post install script, so it didn't work. So do not try it. I'll try to fix it now, so be patient.
Edit 2: Now there is pyKake 0.5.0-8, it should work, but I'm not sure yet.
Edit 3: There is still something broken in post remove script in version 0.5.0-8 (I hope that is in it). So you can't remove application. Means, you had to re-flash the device to get rid of pykake. So if you don't want to do that, do not install this now. I will inform here, when it is secure to do so. (And after all, it is in Extras-devel, so do it in your own risk.)
