segfault on exit after using GRASS layer

[strk]

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

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

Here's a backtrace:

Program received signal SIGSEGV, Segmentation fault.

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)
