Can't reproduce exactly this error, but I'm having other fun with QGIS-GRASS. Examples:
- load the 'alaska' shapefile from QGIS sample dataset
- enable on the fly projection
- save the project
- quit qgis, start it again
- load the project
- Open mapset -> spearfish60/PERMANENT
- Create new GRASS vector
- click any button in the GRASS Digit tool - segfault:

I forgot to add that I can reproduce this on two machines - one amd64 and one i386. I'm referring to fresh SVN checkout 7373, built and running against QT 4.3.1.

Good news is that I can reproduce the first one, in fact it's sufficient for me just to enable projections, add new grass vector and push any digitizing button (no need to open/save alaska layer).
Worse news is that so far I don't know how to fix it correctly: if projections are enabled, points are being transformed from SRS of layer which doesn't exist yet in QGIS (thus the crash). But there are some limitations in plugin API that prevent finding out reference of layer which has been newly added...
Also I'm not able to reproduce the second case you're describing... can you build with debug information and paste more verbose output in console?

My QGIS is built with debug (by "CMAKE_BUILD_TYPE="Debug"; export CMAKE_BUILD_TYPE" before "cmake" - is that OK?). What I habe pasted is all it says.

AFAIK this will not work. I know about these possibilities:
- set it in ccmake configuration utility
- set it as argument for cmake: cmake -DCMAKE_BUILD_TYPE=Debug

Thansk fo the hint. This works.
Getting back to error case 2 - I still can reproduce it. On two machines - amd64 with QGIS 0.9.1 SVN 7389 built and running against QT 4.3.2, and the same SVN checkout on i386 against QT 4.3.1. After enabling debug there seems to be no any information more. Pasting few of the last QGIS words before the crash in GDB:

In Linux Debian I have not this problem.
Are you referring to case 1, 2 or both?
Can you give more details about your platform: Debian version, architectire, QT release, QGIS SVN checkout?

Getting back to error case 2 - I still can reproduce it.
Update: I can reproduce it *only* in GDB. Outside GDB it does not crash at this point anymore (but it really used to in previous SVN revisoins). There is a noticable delay when I open the mapset still, but no crash anymore. At first I thought that building with debug 'fixed' this, but after re-building without debug and re-installing no crash anyway. Maybe I just missed something (or Elves are helping QGIS team to get rid of nasty bugs before 0.9.1 release).

The problem with new layer has been fixed in r8057.
Since the second problem is unreproducible, I'm closing this ticket, file a new one if the bug arises again, open a new ticket.

Is this still a problem? If so, please provide more input about the mapset you're using, if possible provide backtrace with QGIS built with debug support.
