High, again me!

I did follow Andy's advice and followed 3 times the tutorial, with good 
results. I'm feeling more familiar now with Kicad. But....

Now I restarted with my own (of course more complex..) project. I fixed all ERC 
problems (result is 0 errors) and started to check for the missing airwires in 
the board with funny results. Let's take out one example:

In the scematic there are 10 transistors BC550 (Q1-Q10). All transistors have 
no airwires. I let Q1-Q5 unchanged and changed only Q6-Q10 to "TO92" kicad 
footprint, reloaded the partslist and: ALL transistors had airwires!?!?! 

Now I changed Q1-Q10 back to transistors-npn-TO92 from the imported eagle-libs. 
Result: Q1-Q8 had airwires, Q9 and Q10 not!?!?! Very funny. I tried it with the 
latest 2008-version and compiled the newest 2009 stable, with the same results.

At my point of view there are 2 possible reasons for this behaviour: kicad bug 
or a general fault with in the sch-file.

Does anyone have a tip for me??

Thank you for any help!
