sane-backends Trace/BPT trap: 5 after port upgrade

[leonfauster@…]

sane-backends was working fine with this scanner "Canon CanoScan N1240U/LiDE30"

after upgrading all outdated ports i noticed the "Trace/BPT trap: 5" message.

scanning works but

$ scanimage --resolution 300 --mode Color -l 0 --format tiff -x 215 -y 297 > tmp3.tif

$ echo $?

activating the older compat lib helps to get expected behaviour

  libusb-compat @0.1.4_0+universal (active)
  libusb-compat @0.1.5_0+universal

$ scanimage -L
device `plustek:libusb:020:001' is a Canon CanoScan N1240U/LiDE30 flatbed scanner

$ echo $?
0

In the future, please Cc the port maintainers (port info --maintainers sane-backends).

I have migrated my scan station to 10.11. (El Capitan) and the same behaviour persists. Fresh installed OS and macports and scanimage -L exits with non zero status. Downgrading libusb-compat @0.1.4 solved it.
