Thank you, brethren,
for at least having a look at my problem.

But noboday played an Aprils fool on me, there is no alias. Anyway, with that alias the error should occur without "-d" switch, too.

Well, I already gave up looking for the reason of the debugging error and I'm spicing my beautiful code with nasty log prints. This way I might not need the debugger.

Cheers and happy new year!
