 Sorry for the weird Summary, but this is how I reproduce:

  1. start qgis
  1. add grass vector layer
  1. edit grass vector layer
  1. close the grass vector layer editing window (w/out touching anything
 else)
  1. close the main qgis window, w/out saving

 Here's a backtrace:
 {{{
 Program received signal SIGSEGV, Segmentation fault.
 0x0000000000000001 in ?? ()

 #8  0x0000000000533d6f in main ()
 }}}

 Sounds like a missing handling of the grass editor window close button.

 Note this is from the 1.7.0 branch, commit 2516c38 (there's no 1.7.0
 version in trac)
