trace:
$ ./wireshark 
17:30:27          Err  Duplicate protocol name "SERCOS III V1.1"! This might be
caused by an inappropriate plugin or a development error.
Aborted (core dumped)

Here's the back trace

As user root however it starts fine (althought I didn't realized that warning
message before, b/c I often use kdesu to start wireshark) :

n22 ~ # /home/tfoerste/devel/wireshark/wireshark 
Can't open Python registration file:
/usr/local/lib/wireshark/python/1.7.0/register-dissector.py
17:35:04          Warn openSAFETY - Profinet IO heuristic dissector cannot be
registered, openSAFETY/PNIO native dissection.


And yes, I've set this : WIRESHARK_RUN_FROM_BUILD_DIRECTORY=1
