Bug#152128: vcg: segfault on PowerPC

Dear Jeffery, 

Thank you for your bug report. I will try and help you. 

I am working on a new version of VCG, Do not have much internet time,
just about 1-2h a week. I will need another 2-3 months before i have
this version ready.

Are these bugs showstoppers? It seems you have a workaround. I would
like to see if we can get a non-gui version running of the layout
engine and then run the program remotely for debugging. 

I am sure there are some debian remote testing systems available.

Would it be possible to start the program in GDB and then let it crash?
