Comment(by kargig):

 I'm lucky enough to keep my old TBB dirs. So I made some tests to find out
 which one used to work. Here are the results:

 2.3.25-2-Linux | Tor 0.2.4.10 | Works
 2.3.25-4-Linux | Tor 0.2.4.10 | Does not work, throws
 connection_ap_get_begincell_flags(): Bug
 2.3.25-5-Linux | Tor 0.2.4.10 | Does not work, throws
 connection_ap_get_begincell_flags(): Bug
 2.3.25-6-Linux | Tor 0.2.4.11 | Does not work, throws
 connection_ap_get_begincell_flags(): Bug

 Then I compared my torrcs in every version and I found that in
 2.3.25-2-Linux I only used one SocksPort with IPv6Traffic and my current
 torrc had 2 SocksPort defined. One with IPv6Traffic and one without. The
 problem appeared because TBB was using the one without IPv6 traffic:
 SocksPort 9150

 As soon as I replaced it with: SocksPort 9150 IPv6Traffic
 the error message got away.

 So obviously it was a problem on my client's side. Maybe the error msg
 could have been a bit more descriptive though about the problem (e.g. "No
 IPv6 functionality enabled on the SocksPort")

 thanks anyway
