I am getting a segfault on Linux openSUSE 13.2, when i create a footprint with the python scripting footprint wizard. I have test it with R6154, the footprint wizard works as well. After R6155 i become always a segfault, if i create a new footprint with the python scripting wizard. On Win7 it's looks like good.

Steps to reproduce:

1. load Board project
2. click on Footprint Editor Icon
3. In Footprint Editor click on "New footprint using the footprint wizard"
4. click on "select the wizard script to load and run"
5. select a footprint

Now the footprint is loaded and the new message windows is shown. Now i export it to the editor, if i click on the export icon

6. click on the export icon, kicad is crashed.

Here is a Backtrace from gdb:

I think there is a little bug in the Clear() Function?

pcbnew/footprint_wizard_frame.cpp:684
pcbnew/footprint_wizard_frame.cpp: m_messageWindow->Clear();

I have update my openSUSE13.2 system, recompile the R6154 version and it works well, but after R6155 it does not work.

[jean-pierre charras (jp-charras)]

I do not have this crash.
I think I fixed it in rev 6165 (from your trace), but I cannot be sure.
Can you test this rev 6165?

[Michael Kruschinsky (proteusmk)]

I have test the R6165 developer version and in this version the footprint wizard does not crashed and it works, thank you!!!. I try test it tomorrow on windows win7 and let you know tomorrow.
