Cannot debug construct with pycharm

[volker....@inqbus.de]

Hi!

When I try to debug  the following one line "program"

from construct import Struct, Array, UBInt8, UBInt16

utilizing pycharm I get the following stack-trace:

/home/volker/workspace/hamm.can4/bin/python2.7 /opt/pycharm-community-4.0.6/helpers/pydev/pydevd.py --multiproc --client 127.0.0.1 --port 47805 --file /home/volker/workspace/hamm.can4/hamm.can
/src/hamm/can/storecan/multi_packet.py

Connected to pydev debugger (build 139.1659)
pydev debugger: process 21948 is connecting

Process finished with exit code 1

What am I doing wrong?

Any help appreciated

I forgot to mention that any code programmed with consturct runs perfectly. Only debugging is not possible.
