this=0x0 in PART_LIB::Save looks very suspicious.

Don't just say latest, specify the revision.

[Nick Østergaard (nickoe)]

Seems liek it was introduced in 5072, where it segfaults for me. 5071 did not segfault.

[jean-pierre charras (jp-charras)]

Some fixes are made in rev 5101. Please try it.

[Nick Østergaard (nickoe)]

Hi Jean-Pierre, sorry for not noting, but I also did try with Version: (2014-08-26 BZR 5101)-kicad Release build and it still segfaults. I can try to build a Debug build if needed.

Can you not replicate?

[jean-pierre charras (jp-charras)]

OK. I am now able to reproduce this crash.

[Nick Østergaard (nickoe)]

I confirm it is fixed now.
