Well, Soren, I already told I have test box with serial console and
would be very happy to help track these bugs down (actually, I've already
made an account for you there -- so just contact me privately, please ;-)

I realize that at the very moment it would be inappropriate to deep
digging due to RC stage for 4.6. But, sooner or later (and I personally
prefer sooner, you know :) this should be fixed.


Sincerely,
D.Marck                                   [DM5020, DM268-RIPE, DM3-RIPN]
